If a car is speeding down a road at 40 (mph), how long is the stopping distance compared to the stopping distance if the driver were going at the posted speed limit of 25 ?

Express your answer as a multiple of the stopping distance at 25

V1^2 / V2^2 = (40)^2 / (25)^2 = 2.56.
Therefore, the stopping distance at 40
mph is 2.56 times the stopping distance
at 25mph.
