Jack walked 3 1/3 miles in 4/3 hours. If he walked at a constant rate, how far did he walk in 15 minutes?

Answer 1

15 minutes = 15/60 = 1/5 of an hour

3 1/3 = 10/3 miles in 4/3 hours

10/3 miles in 4/3 hours

10/3)/(4/3) = 5/2 = 2 1/2 times as many miles as hours

2.5 x 1/5 = (5/2)(1/5) = 1/2 mile in 15 minutes
