An automated warehouse vehicle travels along a straight guideway. After 18 s, it has travelled 54 m from its starting point. It then continues at a constant speed of 5.0 m/s.
A checkpoint on the guideway is 150 m from the starting point.
Calculate the total time from the vehicle leaving its starting point to the vehicle reaching the checkpoint.
