Question

A cyclist rides his bike at a rate of

11
feet per second. What is this rate in miles per hour? How many miles will the cyclist travel in
3
hours? In your computations, use the fact that
1
mile is equal to
5280
feet. Do not round your answers.

Answer 1

The rate in miles per hour is: 7.5
First you would multiply 60 by 60 because there is 60 minutes in an hour and 60 seconds in a minute. Then you would multiply by 11 then divide by 5280 because there’s 5280 feet in a mile

In 3 hours they would travel: 22.5 miles
You would multiply 7.5 times 3
