Quarter-mile or 1 ⁄ 4 mile may refer to: A dragstrip competition or vehicle test in motorsport, where cars or motorcycles compete for the shortest time from a standing start to the end of a straight 1 ⁄ 4 mile (0.40 km) track; The 440-yard dash, a sprint footrace in track and field competition on a 440 yards (1,320 ft; 400 m; 0.25 mi) oval
Although a quarter mile (1320 feet, 402 m) is the best known measure for a drag track, many tracks are eighth mile (201 m) tracks, and the premiere classes will run 1,000 foot (304.8 m) races. The race is begun from a standing start which allows three factors to affect the outcome of the race: reaction time, power/weight ratio, and traction.
Some drag strips are even shorter and run 660 feet, 201 m, or 1/8 mile. The 1,000 foot distance is now also popular with bracket racing, especially in meets where there are 1/8 mile cars and 1/4 mile cars racing together, and is used by the revived American Drag Racing League for its primary classes (not Jr Dragster).
A Suzuki GSX-R1000 at a drag strip – a 2006 model once recorded a 0 to 60 mph time of 2.35 seconds. This is a list of street legal production motorcycles ranked by acceleration from a standing start, limited to 0 to 60 mph times of under 3.5 seconds, and 1 ⁄ 4-mile times of under 12 seconds.
The child's quarter midget track is one quarter that length, or 1 ⁄ 20 mile (264 feet; 80 m). An adult-size midget in the 1940s and 1980s could reach 120 mph (190 km/h), while the single-cylinder 7 cu in (110 cc) quarter midget engine could make available a speed of 30 mph (48 km/h) in a rookie class (called novices), or one-quarter the speed ...
For example, each additional 1000 feet adds 2 × π × 1000 ≈ 6,283 feet (1.0340 nautical miles) around the whole Earth. In other words, each kilometre altitude increases the distance by 15.7 cm, per kilometre travelled. The higher efficiency far exceeds the negligible distance added. [citation needed]
Car and Driver. length of the rollout depends on the diameter of the tire and where the driver chooses to position the car at the start. Although the rollout distance is typically only a foot or so of a quarter-mile, it can affect the elapsed time by as much as 0.3 second, Markus, Frank; Brantley, Brian; Lutz, Cory (2017-02-20).
