Thanks for the answer. Where did the (60) come from in the equation to work out the distance MN?

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)
