Thanks for the answer. When working out the distance MN where did the 60 come from in the equation ½(0-60÷−12) (60)

60 is my v₀ (initial speed) which I have already found. -12 is my acceleration. (final velocity - initial velocity)/time = acceleration. So from this eqn I made time the subject to get (0-60)/(-12)
