Question 1138720: Manuel is driving to Atlanta. Suppose that the distance to his destination (in miles) is a linear function of his total driving time (in minutes). Manuel has
48 miles to his destination after 20 minutes of driving, and he has 25.9 miles to his destination after 46 minutes of driving. How many miles will he have to his destination after 60
minutes of driving?

You can put this solution on YOUR website!
Points (x,y) , (driving time, miles to destination);
(20, 48) and (46, 25.9)

y-48=%28%2825.9-48%29%2F%2846-20%29%29%28x-20%29
Simplify and solve for y in terms of x.
