Grace's car left four skid marks on the road surface during a highway accident. Two of the skid marks were each 52 feet and two
Mashcka [7]

Answer:

The skid distance to be used is 54 feet.

Step-by-step explanation:

Given:

Four skid marks on the highway.

52,52,56,56  in feet.

We have to find the skid distance.

The skid distance that will be used to further calculate the skid speed is actually the mean skid distance.

Mean skid distance (m) :

⇒ (m)=\frac{Sum\ of \ the\ skid\ marks }{Number\ of\ skid\ marks}

⇒ (m) =\frac{52+52+56+56}{4}

⇒ (m) =\frac{216}{4}

⇒ (m)=54  feet.

So the skid distance to be used is 54 feet.
