Question

An accident investigator measured the skid marks of one of the vehicles involved in an accident. Thelength of the skid marks was 250 feet. Use the formula s=1(24d) (?"s equals square root of 24*d") tofind the speed of the vehicle before the brakes were applied. Round your answer to the nearesttenth. The units are mi/hr

Answer 1

Given the equation:

$s=\sqrt[]{24d}$

Where d is the distance and (s) is the speed

We will find the value of (s) when d = 250 feet

So, substitute with d = 250, and solve for (s)

$s=\sqrt[]{24\cdot250}=\sqrt[]{6000}\approx77.459667$

Rounding to the nearest tenth

so, the answer will be:

Speed = s = 77.5 mi/hr
