A car that was being pursued by the police was at Jones Beach at exactly 9:18 pm (t = 9.3) and passed Oak Beach (15 miles from Jones Beach) at exactly 9:30 pm, where it was overtaken by the police.

How fast was the car traveling?

MPH?

How far was the car from jones beach at time t?

Solution

How fast was the car traveling?

velocity = miles / time

9:18 ---> t=9.3

9;30 ----> t = 9.42

vel = 15 / ( 9.42-9.3)

velocity = 125 miles / sec

velocity = 125 miles/ sec * ( 60 sec / 1 hour) = 7500 miles / hour
