Asked by Loy

The formula is S=2 times the square root of 5 times L. S equals the estimated speed of a car and L equals the length of the skid marks prior to the accident.

100=2(square root of 5x)

I have no idea how to solve this
Answered by Reiny
2√(5x) = 100
√(5x) = 50
square both sides
5x = 2500
x = 500
