Question 687639
"The distance a pickup truck requires to stop varies directly with the square of the speed. 
d = k*s
----------------------
Solve for "k" using "A pickup truck traveling on dry pavement can stop in 85 feet when traveling at 55 miles per hour."
---
85 = k/55
k = 55*85 = 4675
------
Equation:
d = 4675/s
-----

 What distance will the truck take to stop if its traveling at 70 miles per hour?"
---
d = 4675/70
distance = 66.79 feet
