Answer:

The answer is "The cops were correct because the average speed would have been about 39.73 miles per hour as per the calculations."

Step-by-step explanation:

Finding the average skid distance:

Average=\frac{70+71+72}{3}=\frac{213}{3}=71

Calculating the skid:  

S=\sqrt{30 \times D \times f\times n}\\\\  

   =\sqrt{30 \times 71 \times 0.78\times 0.95}\\\\=\sqrt{1,578.33}\\\\=39.73
