To find the speed of the vehicle, we use the formula s = √(30d), where d = 125 feet.
s = √(30*125)
s = √(3750)
s ≈ 61.23 miles per hour
Therefore, the approximate speed of the vehicle was about 61 miles per hour.
Police can estimate the speed of a vehicle before the brakes are applied using the formula , where s is the speed in miles per hour and d is the length of the vehicle’s skid marks. What was the approximate speed of a vehicle that left skid marks measuring 125 feet?
