Question

3 using the table, find the unit rate for each runner.
runner laps time
martha 20 32.5 minutes
allison 16 25 minutes
rachel 17 27.2 minutes

Explanation:

Step1: Calculate Martha's unit rate

Unit rate = $\frac{\text{Laps}}{\text{Time}} = \frac{20}{32.5} = 0.615$ laps per minute

Step2: Calculate Allison's unit rate

Unit rate = $\frac{\text{Laps}}{\text{Time}} = \frac{16}{25} = 0.64$ laps per minute

Step3: Calculate Rachel's unit rate

Unit rate = $\frac{\text{Laps}}{\text{Time}} = \frac{17}{27.2} = 0.625$ laps per minute

Answer:

• Martha: 0.615 laps per minute
• Allison: 0.64 laps per minute
• Rachel: 0.625 laps per minute
