Question 7718
As speed increases ...
- the braking distance does not change.
- the braking distance increases.
- the braking distance decreases.
Show answer and explanation
Correct answer: the braking distance increases.
The faster you go, the more meters the car travels from the moment you press the brake pedal until it stops. Braking distance increases with the square of speed, so at twice the speed you need four times the distance. In the image, the orange arrow marks the braking distance, which begins where the reaction distance ends.
