How to Calculate Track Speeds:
The formula is _
Speed = Distance divided by Time.

Distance is Track Length.
Convert Lap Time into seconds from hours: ( One hour is 3600 seconds)

For a 23 second lap at Richmond (.750 miles): Speed = .750 x (3600/23), = .750 x 156.521739 = a speed of 117.391mph

For a 47 second lap at Daytona (2.5 miles) would be: Speed = 2.5 x (3600/47), = 2.5 x 76.595745 = 191.489 mph.

S = D/T where ( T=3600/Qualifying time)
S x T = D

Using the information given at the left, calculate the following speeds acheived in qualifying.

1.Drivers at Dover had the following qualifying times.
Driver A - 22.869 , Driver B - 22.946, Driver C - 22.756
Pick the correct calculation.

Driver A = 156.8900 mph
Driver B = 156.8900
Driver C = 156.8900
None above are correct

2. Drivers at Richmond had the following qualifying times.
Driver A - 22.869 , Driver B - 22.946, Driver C - 22.756

Driver A = 118.6500
Driver B = 118.6500
Driver C = 118.6500
