A jet airliner flies 4,100 km from New York City to San Francisco in 4.25 hours. What is the average speed?
Understand the Problem
The question is asking for the calculation of average speed based on the distance flown and the time taken. To solve it, we will use the formula for average speed, which is distance divided by time.
Answer
964.71
Answer for screen readers
The average speed is approximately $964.71$ km/h.
Steps to Solve
- Identify the formula for average speed
The formula to calculate average speed is given by: $$ \text{Average Speed} = \frac{\text{Distance}}{\text{Time}} $$
- Input the distance and time
From the problem, the distance flown is 4,100 km and the time taken is 4.25 hours.
- Substitute the values into the formula
Now, substituting the values into the formula: $$ \text{Average Speed} = \frac{4100 \text{ km}}{4.25 \text{ h}} $$
- Perform the calculation
Calculate the average speed: $$ \text{Average Speed} = \frac{4100}{4.25} \approx 964.71 \text{ km/h} $$
The average speed is approximately $964.71$ km/h.
More Information
Average speed measures how fast an object is moving over a specific distance within a given time. In this case, the jet airliner travels a significant distance at a high speed.
Tips
- Confusing units: Make sure to keep the distance in kilometers and time in hours to avoid incorrect calculations.
- Misreading time: If the time is given in decimal hours, ensure to convert it correctly if necessary.
