After an accident the police determines the speed at which the car had been traveling by the formula below.
This formula can be used to approximate speed r, in miles per hour, of a car that left skid marks of length L, in feet.
-------
How far will the car skid at 67 miles per hour?
r = 2√5L
---
67 = 2*sqrt(5L)
33.5 = sqrt(5L)
5L = 33.5^2 = 1122.25
Length = 224.45 feet
