You are driving a car with good brakes and new tyres on a dry asphalt road. How many metres is the stopping distance if your speed is 50 km/h and you react in 1.5 seconds?

  • Incorrect: 50 metres
  • Correct: 30 metres
  • Incorrect: 10 metres
  • Incorrect: 5 metres

First, consider the calculations of stopping distance, reaction distance and breaking distance.

Reaction distance:

  • remove the zero in the speed * reaction time * 3
  • 5 * 1.5 * 3 = 22.5 (rounded to 23 metres)

Braking distance:

  • remove the zero in the speed * remove the zero in the speed * 0.4
  • 5 * 5 * 0.4 = 10 metres

Stopping distance:

  • reaction distance + braking distance
  • 23 + 10 = 33 (rounded to 30 metres)
