Answer:

Yes the car was speeding

Step-by-step explanation:

                s = √(30fd) where

  • s is the speed of the car in mph
  • f is the coefficient of friction for the road
  • d is the length in feet of the skid marks

Substitute d = 41.5 and f = 0.8 into the equation:

    s = √(30 x 0.8 x 41.5)

⇒  s = √(996)

⇒  s = 31.55946768...

Therefore, for these data, the speed of the car was 31.56 mph (to the nearest hundredth)

The speed limit was 30 mph, therefore the car was speeding as 31.56 > 30
