If a vehicle is travelling at 55 km/h and increases its speed to 110 km/h...

A)The braking distance will double.
B)It will not affect the braking distance.
C)The braking distance will increase in greater proportion than the increase in speed.Correct
The braking distance increases in greater proportion than the increase in speed, for example, if at 40 km/h the braking distance was 9 metres, at 80 km/h it would be 36 metres, so the speed would have doubled while the braking distance would be four times greater.
The braking distance increases in greater proportion than the speed.
The braking distance increases in greater proportion than the speed.
