The quarter mile (402 meters, 440 yards, or 1,320 feet) is a distance generally used for drag racing two objects, and is an excellent way to compare the speed and acceleration of two objects. Although a quarter mile is the best known measure for a drag track, many tracks are eighth mile tracks. The race is generally begun with a standing start which allows three factors to affect the outcome of the race: reaction time, power and traction. The most common example use of this distance is in automobile Drag Racing.
