Question

If you double your speed on a highway, how many times does your braking distance increase?

1) 2 times
2) 3 times
3) 4 times
4) 5 times

Answer 1

When you double your speed on a highway, your braking distance increases by 4 times.

Step-by-step explanation:

When you double your speed on a highway, your braking distance does not simply double, it increases quadratically. The braking distance is directly proportional to the square of the speed. This means that if you double your speed, your braking distance will increase by 4 times.
