Based on the measurement of the distance of the skid marks, the speed of the car before the brakes were applied is 40.62 ft/s and in miles per hour it was 27.70 miles per hour.

How fast was the car going before the brakes were applied?

The speed of the car before the brakes were applied can be found as:

= √(30 x distance of skid marks)

Solving gives:

= √ (30 x 55)

= √1,650

= 40.62 ft/s

In miles per hour, this can be found to be:
= Speed in feet per second x 0.681818

= 40.62 x 0.681818

= 27.70 miles per hour
