Question

A cyclist rides his bike at a rate of 18 miles per hour. What is this rate in miles per minute? How many miles will the cyclist travel in 20 minutes? Do not roundyour answers.Rate:Distance traveled in 20 minutes:

Answer 1

Okay, here we need to calculate the rate in miles per minute:

`\begin{gathered} 18(miles)/(hour)\cdot\frac{1\text{ hour}}{60\text{ minutes}} \\ =\frac{18\text{ miles}}{60\text{ minutes}} \\ =0.3\text{ miles/minutes} \end{gathered}`

The rate in miles per minute is 0.3 miles/minute.

To know how many miles will the cyclist travel in 20 minutes we are going to multiply the miles per minute by 20 minutes, let's do it:

`\frac{0.3\text{ miles}}{minute}\cdot20\text{ minutes=}6\text{ miles}`

Finally we obtain:

Rate: 0.3 miles/minute

Distance traveled in 20 minutes: 6 miles
