Question

Kevin traveled at a constant speed on the highway from Hickory Hills to Chicago in 20 minutes. The distance from Hickory Hills to Chicago is 17 miles. How fast was Kevin driving?

Answer 1

Answer:
`V=51\ (mi)/(h)`

Explanation:

You need to used the following formula:

`V=(d)/(t)`

Where "V" is the speed, "d" is the distance and "t" is the time.

In this case you know that Kevin traveled at a constant speed on the highway from Hickory Hills to Chicago in 20 minutes (which is
`(1)/(3)\ h`) and the distance is 17 miles. Then, you can identify that:

`t=(1)/(3)\ h\\\\d=17\ mi`

Therefore, knowing these values, you can substitute them into the formula. Then, you get:

`V=(17\ mi)/((1)/(3)\ h)\\\\V=51\ (mi)/(h)`
