A car, travelling on a straight road, brakes and comes to a stop. Which row gives the expression for calculating the thinking distance and gives a variable that affects thinking distance?
Aexpression for calculating thinking distance: braking distance + stopping distance, variable that affects thinking distance: load carried
Bexpression for calculating thinking distance: braking distance + stopping distance, variable that affects thinking distance: speed of car
Cexpression for calculating thinking distance: stopping distance – braking distance, variable that affects thinking distance: load carried
Dexpression for calculating thinking distance: stopping distance – braking distance, variable that affects thinking distance: speed of car
✓ Correct answer
D: expression for calculating thinking distance: stopping distance – braking distance, variable that affects thinking distance: speed of car
