Question

A cyclist rides her bike at a speed of 20 kilometers per hour. What is this speed in miles peer hour? How many miles will the cyclist travel in 3 hours? In your computations, assume that mile is equal to 1.6 kilometers.

Answer 1

20 km/hr * 1/1.6
20* (1/1.6) = 12.5 miles per hour

In three hours: 12.5*3
                      : 37.5 miles
