To estimate the speed of a car, v, in miles per hour, based on the length, L, in feet, of its skid marks when suddenly braking on a dry, asphalt road. At the scene of an accident, a police officer measures a car's skid marks to be 242 feet long. Approximately how fast was the car traveling? Round your answer to the nearest tenth (one decimal place) of a unit.

69.6 miles per hour

Step-by-step explanation:

Length of the skid marks = 242 feet

The formula used for the velocity is

where, L is the length of skid marks in feet and the velocity obtain has the units of miles per hour.

By substituting the value

v = 69.6 miles per hour

Thus, the speed of the car at the time of accident is 69.6 miles per hour.

x=17

step-by-step explanation:

solve 3x-24=x+10

then that makes it 2x=34 because you subtract an x from both sides to get rid of the one on the right, and then you add 24 to both sides to get rid of the 24 on the left

divide by both sides by 2 to get your answer so that you can get your answer

no solution

step-by-step explanation:

there is not enough information in the problem to solve.
