A brand new Rolls-Royce rolls off the back of a truck as it is being delivered to its owner. It lands on its wheels. The truck is traveling along a straight road at a constant speed of 72km/h (20m/s). The Rolls-Royce slows down at a constant rate, coming to a stop over a distance of 240m. It is a full minute before the truck driver realizes that the precious load is missing. The driver brakes immediately leaving a 25m long skid mark on the road. The driver's reaction time (time interval between noticing the problem and depressing the brake) is 0.5s. How far back is the Rolls-Royce when the truck stops?
