Suppose you are driving on the interstate at 88 mph when you see a highway patrol car parked up ahead. You apply your brakes, decelerating at a constant rate of 3.9 mph/sec until you have reduced your speed to 65 mph. You then maintain a constant speed of 65 mph. You pass the patrol car 17 seconds after you initially applied the brakes and are relieved that he doesn't pull out after you. How far away was the highway patrol car when you first saw it?
