Problem 1: Finding The Median

• The 1st problem involves finding the median in a dataset.
• Given five students' math test scores: 97, 92, 81, 90, and 73.
• "Median" is the middle value.
• Arrange numbers from least to greatest: 73, 81, 90, 92, 97.
• Find the number directly in the middle of the sorted set, so 90 is the median score.

Problem 2: Calculating Distance

• Question 2 involves calculating distance traveled.
• A platoon marches for three hours at six miles per hour.
• The goal is to determine how far the platoon goes in those three hours.
• Moving at six miles per hour, the platoon travels six miles every hour.
• Multiply six miles per hour by three hours to find total distance: 6 * 3 = 18 miles.
• The platoon travels a total of 18 miles.

Problem 3: Hot Dog Challenge

• Jack eats three hot dogs per minute, while Jeff eats two hot dogs per minute.
• The goal is to determine how many total hot dogs they eat in 12 minutes.
• Find how many hot dogs Jack eats in 12 minutes: 3 hotdogs/minute * 12 minutes = 36 hot dogs.
• Find how many hot dogs Jeff eats in 12 minutes: 2 hotdogs/minute * 12 minutes = 24 hot dogs.
• Total hot dogs eaten: 36 + 24 = 60 hot dogs in total.
• Together, Jack and Jeff eat a total of 60 hot dogs in 12 minutes.

Problem 4: Mileage Calculations

• A marathon runner challenges 11 friends to run 26 miles.
• The goal is to find the total miles run by all friends.
• Multiply 11 friends by 26 miles: 11 * 26 = 286 miles.
• The total mileage ran by all friends equals 286 miles.

Quick tip Time savers

• Start by writing down the numbers you expect to use when approaching math problems.
• Do not be intimidated by numbers, the question is often hidden within the context.
• Begin to associate numbers together to process questions faster which saves time in the long run.

Arithmetic Questions Source

• The arithmetic questions are sourced from the "ASVAB for Dummies" study guide.
• The instructor bought the latest version of the ASVAB for Dummies from Amazon.
• Questions from the "ASVAB for Dummies" book were explained because understanding comes easier to some by hearing.

Multiplication Problem

• Seven times four equals 28.

Rectangle Width Problem

• Find the width of a rectangular vegetable garden.
• The perimeter of the garden is 150 feet.
• The length of the garden is 50 feet.
• The perimeter of a rectangle is calculated by adding up all four sides: length + width + length + width.
• Given the equation: 50 + width + 50 + width = 150 feet.
• Combined length = 50 * 2 = 100 feet.
• Calculate for the combined width: 150 - 100 = 50 feet.
• There are two widths, so 50 is divided by 2 which means each width is 25 feet.
• The answer: 25 feet. Calculating all sides: 25 + 25 + 50 + 50 = 150 feet.

Percentage Problem

• Diane's meal costs $85; her client's costs $110, and the restaurant adds a 15% gratuity.
• Total cost: $85 + $110 = $195.
• Convert 15% to a decimal: 0.15.
• Multiply the total cost by 0.15: $195 * 0.15 = $29.25.
• The 15% gratuity is $29.25.

Fraction Problem

• Farmer Beth sells her 320-acre farm for $3,000 per acre and gives the buyer $96,000 worth of land.
• Need to find the fraction of Farmer Beth's land that the buyer is getting.
• The total value of Farmer Beth's land equals $960,000 as a product of 320 x $3,000.
• The fraction of land the buyer is getting is $96,000/$960,000.
• Simplify the fraction.
• This gives 96/960 by removing three zeros from both numbers.
• 96 is one-tenth of 960, translating into the simplified fraction of 1/10.
• The buyer is getting 1/10 of Farmer Beth's land.
• These equations are verifiable: $96,000 is one-tenth of $960,000 , 96 is one tenth of 960, 96,000 is one tenth of 960,000.
• One hour of intense studying is an accomplishment toward your path.
• Subscribers will be granted assistance, sharing this video will also do the same for ASVAB applicants or Army recruiters. Success is made by actions, so get up and grind.

Percentage Increase Problem

• Mr. Cameron bought a shirt for $20 and sold it for $26.
• The goal is to find the percentage increase in price.
• A percentage is always based out of 100 (X/100).
• The difference between the selling price and the original price is $6.
• Cross-multiplication 20x = 6 * 100
• 20x = 600
• Dividing both sides by 20 isolates X
• X = 30%
• Mr. Cameron made a 30% profit.

Time Fraction Problem

• Portions of an enlisted person's time are allocated between activities in the military.
• Activities include 1/4 for sleeping and eating, 1/12 standing at attention, 1/6 exercising, and 2/5 working.
• The goal is to find the discretionary time amount in hours per day.
• To solve for fractions, a common denominator is needed.
• The common denominator between 4, 12, 6, and 5 is 60.
• Convert fractions to have the same denominator 60: 15/60, 5/60, 10/60, and 24/60.
• Adding fractions with a common denominator requires summing the numerators but not changing the denominator.
• 15+5+10+24 = 54/60 is the fraction of how much time the soldier uses for required tasks
• Remaining time is 6/60.
• Simplify the fraction 6/60 to 1/10.
• One-tenth of the time is used for discretionary purposes.
• Since there are 24 hours in a day, divide 24 by 10.
• 24 divided by 10 is 2.4 hours.

Designer Carpet Cost Problem

• Designer carpet sells for $15 per square yard
• The same carpet is $12.50 at a carpet outlet.
• The objective is to find how much more expensive the designer's carpet is, as a percentage.
• Set up the problem with a percentage-based expression.
• Percentage is anything out of 100
• The difference between $15 and $12.50 is $2.50.
• Set up the cross-multiplication like this, 2.5/12.5=X/100
• Cross multiply to create the expression 12.5X=2.5*100
• Multiply to get 12.5X=250

Percentage-Based Questions

• Percentage is anything out of 100, expressed as x/100.
• To solve percentage-based questions, find the difference between the two values.
• Place the difference over the original price or starting point.
• Cross multiply to find the percentage.
• Rushing through the ASVAB can cause errors

Steve's Fence Problem

• Steve takes 56 hours to paint his fence.
• He works with his three children who each work 7 hours per day.
• To find the total number of workers include Steve and his three children, totaling four workers.
• Each person works at the same rate of 7 hours per day.
• The combined work per day is 4 workers * 7 hours/worker = 28 hours per day.
• To find how many days it will take, divide the total hours by the combined work per day: 56 hours / 28 hours/day = 2 days.

Insider Tips for the ASVAB

• Don't rush through the first five sections: General Science, Arithmetic Reasoning, Math Knowledge, Paragraph Comprehension, and Word Knowledge.
• These sections contribute to the GT score and AFQT score.
• The test may kick you off if you perform poorly on these sections
• Arithmetic Reasoning is crucial for maximizing points and boosting your score.

Dog Treats Percentage Problem

• Cujo and Achilles have 250 dog treats in total.
• The dogs ate 200 treats.
• First find the remainder, which is 250 - 200 = 50
• Percentage is anything out of 100
• Set up the equation as: x/100 = 50/250, where x is the percentage remains
• Then cross multiply to create the expression 250x = 50*100
• Next simplify to 250x = 5000
• Then we divide both sides by 250: x = 5000/250
• Therefore we can calculate the final answer x = 20 percent

Chris and Sailor's Age Problem

• Chris is five times as old as Sailor
• The sum of their ages is 18
• Chris's age can be expressed as C = S * 5, where S is Sailor's age.
• The sum of their ages is C + S = 18.
• Substitute C in the equation: 5S + S = 18.
• Simplify: 6S = 18.
• Divide to find Sailors age: S = 18 / 6 = 3 Years
• To find Chris's age substitute Sailors age : C + 3 = 18
• Therefore we can calculate the final age C = 15
• Therefore, Chris is 15 years old and Sailor is 3 years old.

Solving Equations

• If 5s + s = 18, results in 6s = 18.
• Dividing both sides by 6 gives s = 3, meaning Sailor's age is 3.
• Chris + Sailor's age = 18, substituting Sailor's age gives Chris + 3 = 18.
• Subtracting 3 from both sides shows Chris's age is 15.
• Checking confirms 15 (Chris) + 3 (Sailor) = 18.
• Chris is five times older than Sailor: 3 * 5 = 15, which checks out.

Train Problem

• Train 1 travels at 40 kilometers/miles per hour.
• Train 2 leaves an hour later from the same station, traveling at 50 kilometers/miles per hour.
• After the first hour, Train 1 is 40 km/miles down the track.
• After the second hour, Train 1 is at 80 km/miles (40 + 40).
• In the third hour, Train 1 reaches 120 km/miles, while Train 2 reaches 100 km/miles (50 + 50).
• After four hours, Train 1 is at 160 km/miles and Train 2 is at 150 km/miles.
• In the fifth hour, Train 1 reaches 200 km/miles, and Train 2 also reaches 200 km/miles.
• It takes five hours for Train 2 to overtake Train 1.
• This is because Train 2 gains 10 miles every hour as it tries to catch up to Train 1, which had a one hour head start.
