I've been discussing this with a few people lately and we've come to the conclusion that this formula gives you a mostly accurate number as long as both driver's keep their foot on the throttle all the way through the finish line. As soon as one of the driver's (mainly the second to cross...but both can effect a change) slam the brakes or change the rate of speed as they are crossing the finish it becomes much more of an approximation than an exact science.

The problem is most of our cars are consistantly accelerating all the way through the finishline stripe so the rate of speed isn't constant at any point on the track. Which means if that formula says it was a 5 foot stripe the second car was actually traveling at a slower rate of speed at the exact moment the first car crossed the finishline, than it was when it actually crossed the finishline so it was a little more than 5 feet (even if both kept their foot on the floor). Maybe too small to care about but it all depends on the speed and the rate of acceleration the car is still at.
