It is given to us that the formula to determine the speed of the car is:
where: S = speed in miles per hour
30 = a constant value used in the equation
D = length of the skid marks in feet
f = drag factor for the road surface
n = braking efficiency as a percent
It is also given to us that average length of skid is 60 feet so D=60.
Drag Factor, f=0.75
And Brake efficiency, n=100%=1
Thus, using the given data in the Formula for calculating the speed we get:
miles per hour.
Thus, from the given set of options, the third option which has 37 is the correct option.
