Question 203243: 1.The approximate speed that a car was traveling when the brakes are suddenly applied can be determined by the police using the equation S=4.47L^1/2 where Sis the speed of the car in miles per hour and L is the length of the skid marks left by the tires in feet. If 169-foot long skid marks were left by a car, at what speed was it traveling when the breaks were applied.

Substitute what was given into:
S=4.47sqrt%28L%29%29
.
L = 169
.
S=4.47%2Asqrt%28169%29
S=4.47%2813%29
S=58.11 mph
