Math Problem Statement
When a car makes an emergency stop on dry pavement, it leaves skid marks on the pavement. The speed S, in miles per hour, of the car when the brakes were applied is related to the length L, in feet, of the skid mark. The relationship is S(L) = 5.05 square root L. Calculate the speed of a car that leaves a 70 food skid mark.
