the function d(t)=15t^2-100t gives the distance a car going a certain speed will skid in t seconds. find the time it would take for the car to skid 170 feet
Equate 170 feet to d(t) = 15t^2 - 100t. Rearrange these 3 terms in descending order according to the powers of t. Then solve for t. Use the quadratic formula or some other suitable approach.
