Question

A circular running track is 1/4 mile long. Elena runs on this track, completing each lap in 1/5 of an hour. What is Elena's running speed?

Answer 1

Answer: 1.25 mph

Explanation:

.25 miles per 1/5 hour = .25 miles per 12m

12m x 5 = 60m = 1 hour

.25 x 5 = 1.25 miles

So, 1.25 miles per one hour = 1.25mph
