Question

A cyclist rides his bike at a rate of 15 miles per hour. what is this rate in miles per minute? how many miles will the cyclist travel in 20 minutes? do not round your answers.

Answer 1

0.25 miles per minute, travels 5 miles in 20 minutes

Explanation:

First, we have to find out how many miles he can travel in a minute.

We know that he travels 15 miles every hour, and we know that one hour is 60 minutes.

• 15 mi./ 1 hr = 15 mi. / 60 minutes

So, we can divide 15 miles by 60 minutes in order to get his pace for miles per minute

• 15 ÷ 60 = 0.25 miles per minute

Then we can just multiply 0.25 miles by 20 minutes

• 0.25 × 20 = 5

which gives us 5 miles in 20 minutes
