Question
Police can estimate the speed of a vehicle before the brakes are applied using the formula
0.75d = 30.25 where s is the speed in miles per hour and d is the length of the vehicle's skid
marks. What was the approximate speed of a vehicle that left a skid mark measuring 150 feet?
(1 point)
• about 67 miles per hour
• about 15 miles per hour
• about 11 miles per hour
• about 58 miles per hour

To find the approximate speed of the vehicle, we can plug in the given skid mark length into the formula and solve for speed:
0.75d = 30.25
0.75(150) = 30.25
112.5 = 30.25
s = 112.5 / 0.75
s = 150
Therefore, the approximate speed of the vehicle was about 67 miles per hour.
Therefore, the correct answer is:
- about 67 miles per hour
0.75d = 30.25
0.75(150) = 30.25
112.5 = 30.25
s = 112.5 / 0.75
s = 150
Therefore, the approximate speed of the vehicle was about 67 miles per hour.
Therefore, the correct answer is:
- about 67 miles per hour
