Question

A cyclist rides his bike at a rate of 22 feet per second. What is this rate in miles per hour? How many miles will the cyclist travel in 5 hours? In your computations, use the fact that 1 mile is equal to 5280 feet. Do not round your answers.

Answer 1

22  feet/1 second

miles/hour=5280 feet/3600 seconds

22*3600/1*3600

79,200 feet/3600 seconds

79,200 feet/hour

79,200/5280=15 miles

15 miles per hour is the rate

15*5=75 miles traveled in 5 hours
