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)
