Question

A cyclist rides her bike at a speed of 10 miles per hour. What is this speed in kilometers per hour? How many kilometers will the cyclist travel in 5 hours? In your computations, assume that 1 mile is equal to 1.6 kilometers. Do not round your answers.

Answer 1

1) since 1 mile = 1.6 km, then the speed of 10 miles per hour = 16 km per hour.

2) In 5 hours at the speed of 16 km per hour, the cyclist would travel 80 km.
