In the following exercises, solve. Round approximations to one decimal place. 551. Accident investigation An accident investigator measured the skid marks of one of the vehicles involved in an accident. The length of the skid marks was 175 feet. Use the formula s = 24 d to find the speed of the vehicle before the brakes were applied. Round your answer to the nearest tenth.

You toss a ball into the air at. Heighr of 5 feet. The velocity of the ball was 30 feet per second. You catch the ball 6 feet from the ground. How long was the ball in the air?
Police use the formula:
v = V20L
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 194 feet
long. Approximately how fast was the car traveling? Round
your answer to the nearest tenth (one decimal place) of a
unit.
Answer: The car was traveling at approximately
miles per hour.
Police use the formula:
U = v20L
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 measSures
a car's skid marks to be 193 feet long. Approximately how fast was the car traveling? Round your
answer to the nearest tenth (one decimal place) of a unit.
Answer: The car was traveling at approximately
miles per hour.
