Ever wonder how the average speeds are
calculated at the various tracks? Since there are hundreds of racetracks around the
country that are various lengths, one would imagine that the formula used would be some
scientific, NASA oriented formula. But, contrary to popular belief, the exact same formula
is used for every racetrack, whether it be the bullrings like the Old Dominion Speedway,
or the massive
layout of the Daytona International Speedway.
How to Calculate Track Speeds:
Use the formula Speed = Distance divided by Time. Distance is Track Length, and Lap Time
into Hours. Once hour is 3600 seconds, so the calculation for a 48 second lap at Daytona
(2.5 miles) would be: Speed = 2.5 x (3600/48), = 2.5 x 75 = 187.500 MPH. For a 16 second lap at Old Dominion
Speedway (.375 miles): Speed = .375 x (3600/16), which would be Speed = .375 x 225, which
would equal 84.375 MPH.
