Cindy runs 2 1/3 miles in 2/5 of an hour. How many miles can she run per hr? How many hours does it take her to run 1 mile?

Answer 1

(2 + 1/3) divided by 2/5 = 7/3 divided by 2/5 = 7/3 * 5/2 = 35/6 = 5 and 5/6 mph

The reciprocal is 6/35 hours per mile

which is 6/35*60/1 = 360/35 = 72/7 = 10 and 2/7 mins = 10 minutes and 18 seconds
