Question

A car is traveling at a rate of 40 miles per hour. What is the car's rate in kilometers per hour? How many kilometers will the car travel in 2 hours? In your computations, assume that 1 mile is equal to 1.6 kilometers. Do not round your answers.

Answer 1

40 m/h * 1.6km/1m = 64 km/h
If the car travels 64 km in one hr multiply it by 2 to find the distance traveled in 2 hours.
64 * 2 = 128 km/2hr
