Question

After an accident, police can estimate the speed that a car was traveling by measuring its skid marks. The formula r=2√5L can be used, where r is the speed, in miles per hour, and L is the length of the skid marks, in feet.
Estimate the speed of a car that left skid marks (a) 50 ft long; (b) 180 ft long.

How fast was the car traveling if it left skid marks 50 ft long?
(Simplify your answer. Type an integer or a decimal. Round to the nearest tenth.)
