Study Notes
What is a Unit Rate?
- A unit rate is a measure of the amount of one unit it takes for something to happen in other units.
Examples of Unit Rates
- Miles per hour
- Cost per item
- Earnings per year
- Gallons per minute (flow rate of a hose)
Finding the Unit Rate
- Take a defined period of time and measure the output during that time
- Calculate the output per unit of time (e.g., gallons per minute)
- Alternatively, measure how long it takes to do something that has a known quantity (e.g., driving 100 miles in 2 hours)
Unit Rate Example
- If it takes 3 hours to drive 210 miles, the unit rate is 70 miles per hour (210 miles ÷ 3 hours)
- In this example, the unit rate is used to determine if someone was speeding (exceeding the 65 miles per hour speed limit)
