Ignoring the other cars, the nearest three cars in the drag race are denoted "blue", "white" and "red".  Blue accelerates at 2delta.deltadeltadelta ft/s^2 for the first three second and then at 1ft/s^2 for the remainder of the race.  White accelerates at 15.deltadeltadeltadelta ft/s^2 for the first 400ft but then cannot maintain that speed and decelerates at -0.5ft/s^2 for the remainder of the race.  Red  acclelerates at 30.deltadeltadeltadelta ft/s^2 for 1 second, then 20ft/s^2 for the next second then 18ft/s^2 for the next two seconds and maintains that speed.  Which car is first to reach 1/4 mile (1320 ft) and at what time?
