Easy method: Calculate the reaction distance
Formula: Remove the last digit in the speed, multiply by the reaction time and then by 3.
Example of calculation with a speed of 50 km/h and a reaction time of 1 second:
50 km/h ⇒ 5
5 * 1 * 3 = 15 metres reaction distance
More precise method: Calculate the reaction distance
Formula: d = (s * r) / 3.6
d = reaction distance in metres (to be calculated).
s = speed in km/h.
r = reaction time in seconds.
3.6 = fixed figure for converting km/h to m/s.
Example of calculation with a speed of 50 km/h and a reaction time of 1 second:
(50 * 1) / 3.6 = 13.9 metres reaction distance
