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?

Step-by-step explanation:

You need to used the following formula:

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 ) and the distance is 17 miles. Then, you can identify that:

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

for finding the midpoint of any given 2 pair of points simply add the respective x coordinates with other x coordinate and the y coordinate with other y coordinate and divide them by 2

in your question it will be :

(3+1)/2 for the x coordinate of mid point i.e 2

[8+(-4)]/2 for the y coordinate of midpoint i.e 2

so coordinates of mid point of points (3,8) and (1,-4) will be (2,2)
