Question

By what percent does the braking distance of a car increase, when the speed of the car increases by 13.3 percent? Braking distance is the distance a car travels from the point when the brakes are applied to when the car comes to a complete stop.

Answer 1

When the speed of the car increases by 13.3 percent, the breaking distance increases by 13.3 percent as well.

Increase in the distance of the car

The increase in the distance of the car is calculated as follows;

v = d/t

where;

• d is distance
• t is time
• v is speed

Distance and speed are directly proportional, thus, when the speed of the car increases by 13.3 percent, the breaking distance increases by 13.3 percent as well.
