Francis ran 2 1/2 miles in 7/12 of an hour. how many miles can francis run in one hour?

7/12 of 1 hour:

1 hour = 60 min.

7/12 * 60

7 * 5 = 35

Francis ran 2 1/2 miles in 35 min.

2 1/2 = 5/2

5/2 miles = 35 min

x miles = 60 min

(Cross Multiply)

5/2 * 60 = 35x

5 * 30 = 35x

150 / 35 = x

x = 30 / 7 = 4 2/7 miles

Francis ran 4 2/7 miles in one hour.
