7. Superman is in level flight 6 miles above the ground. His flight plan takes him directly over and past Avon High School. How fast is he flying when the distance between him and AHS is exactly 10 miles
and this distance is increasing at the rate of 40 mph?

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)
