Speed distance and time calculation. 10 points etc, GCSE maths

what is the reaction time you have for a car coming towards you at 25mph at a distance of 10 meters?
ie. how long do u have in time before the vehicle reaches you. I know it's Distance divided by speed, but what is this in seconds

25mph = (25 x 1.6093) = 40.2325kph.
(40.2325/3.6) = 11.176m/sec.
(10/11.176) = 0.895 sec.
