Question

A car travels 0.75 miles every minute. Explain how you could use proportional reasoning to find how far the car travels in one hour.

Answer 1

Answer: Identify the unit rate as 0.75 miles per 1 minute. Since there are 60 minutes in an hour, multiply 0.75 time 60 to find how far the car travels in one hour.

Answer 2

(0.75mi/1min)*(60min/1hour) = (45min/1hour)

By converting minutes into hours and multiplying 60 on the number of miles it travels for 1 minute, you get the number of miles the car has traveled in 60 minutes.
