Early motor vehicles used mechanical … theranos employee cultureWebbAdding reaction distance to braking distance, the stopping distance for Car 1 is 27.1 + 16.3 = 43.4 metres. For Car 2, stopping distance is 25 + 13.9 = 38.9 metres. Car 1 therefore takes 4.5 more metres to stop than Car 2, a 12 per cent increase. We can now see why Car 1 is more likely than Car 2 to hit Sam. signs of australia auslan dictionary
