What is the stopping distance at 70 mph?

Explanation:
Stopping distance is all the distance you travel from the moment you spot a hazard until you come to a stop, and it’s made up of two parts: thinking distance (how far you travel while you react) and braking distance (how far you travel while you slow down). At 70 mph, using a typical reaction time of about 1.5 seconds gives a thinking distance of roughly 46–47 metres. The braking distance on a dry road at that speed is about 50 metres. Add them together and you’re near 96 metres. So 96 metres is the best answer because it matches the standard dry-road stopping distance for 70 mph. The smaller figures don’t fit the scale of distance you’d cover in that time and speed.
