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.

7! = 7×6×5×4×3×2

3! = 3× 2

as 7! is multiple of 3! because 7! contains 3! that is 3× 2 as factor

so 7! /(3! ) = 7× 6× 5× 4

= 42 × 20

= 840

its b) 840✌✌✌
