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.
