Question

A car travels 156 miles in 3 hours and 15 minutes. how many miles does it travel per hour

Answer 1

48 mph

Explanation:

Convert 3 hours 15 minutes to hours.

15 minutes = 15/60 hour = 1/4

So 3 hours 15 mins = 3 1/4 hours = 13/4 hours

156 miles in 13/4 hours ==> speed = 156 ÷ 13/4 = 156 x 4/13 = 48
