Question

Sara can finish 5 laps around the track in 6 minutes. What is her average speed in miles per hour, if it takes 12 laps around the track to run a mile?

Answer 1

9514 1404 393

Answer:

4 1/6 miles per hour

Explanation:

6 minutes is 1/10 hour, so Sara's speed is ...

speed = distance/time

speed = (5/12 mi)/(1/10 h) = 50/12 mi/h

speed = 4 1/6 mi/h

Sara's speed is 4 1/6 miles per hour.
