  • is there a formula?

    i was just wondering if there was some type of formula that could calculate, how many car lengths in a race equal how much time???

    I'm not quite sure but I think atleast in the quarter mile 1 car length equals roughly one tenth of a second. I think Joe might know a better way than that to figure it out though.

      One way to figure it......

      Depends on the speed of the vehicles. At 100 MPH, the lead vehicle is moving at 147 ft/second. That means 1/10th second difference is a 14.7 foot difference, or very close to the length of a car - a 4th Gen is 195" = 16.2 feet.

      At 111 MPH, 1/10th second = exactly the length of a 4th Gen F-Body.
