with 50 km/h = 15m skid

so, 150 km/h = 45m skid

multiply sides by 3, make them proportional to each other!!!

Kinetic energy = (1/2 m) x (speed)²

A car moving 3 times as fast has 9 times as much kinetic energy.

If the force of friction between the tires and the ground
is the same at every speed, then the car has to go 9 times
as far to burn off the increased kinetic energy.

    9 x 15m  =  135 meters
