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 = 187.500mph.
For a 19 second lap at Bristol(.533 miles): Speed = .533 x (3600/19), = .533 x 189.474 = a speed of 100.990mph
