An automobile crash investigator measured the skid marks of one of the vehicles involved in a crash. The length of the skid marks was 144 feet.

Use the formula [tex]s = \sqrt{24d}[/tex], where [tex]s[/tex] is the speed of the vehicle in miles per hour before the brakes were applied, and [tex]d[/tex] is the length of the skid marks in feet, to find the speed of the vehicle before it started braking.

Round your answer to the nearest tenth.

Answer: _____ miles per hour

Answer :

Final answer:

To find the speed of the vehicle before braking, use the formula s = √24d, where s is the speed in mph and d is the length of skid marks in feet.


Explanation:

To find the speed of the vehicle before it started braking, we can use the formula s = √24d, where s is the speed of the vehicle in miles per hour and d is the length of the skid marks in feet.

In this case, the length of the skid marks is given as 144 feet. Plugging this value into the formula, we get:

s = √24 * 144 = 2 * 144 = 288

Therefore, the speed of the vehicle before it started braking is approximately 288 miles per hour.
