A runner sets offfrom a point P at time t = 0, where t is in seconds. The runner starts from rest and accelerates at 1.2 m s−2 for 5 s. For the next 12 s the runner moves at constant speed before decelerating uniformly over a period of 3 s, coming to rest at Q. A cyclist sets offfrom P at time t = 10 and accelerates uniformly for 10 s, before immediately decelerating uniformly to rest at Q at time t = 30.
