because steve ran 100 yard in the time it took dave to run 80, steve is running 1.25 times faster than dave. divide 120 by 1.25 and you find that steve beats dave by 4 yards
Steve wins by 4 yards

1st race took x seconds
In x seconds, Steve travelled 100, while Dave got 80. Therefore, their speed was 100/x and 80/x respectively.
If Steve now travels 120 while Dave still at 100, Steve would take 120/(100/x) while Dave 100/(80/x), or 1.2x seconds for Steve and 1.25x seconds for Dave, so Steve still wins.

the answer lies in the question. the theory of relativity states that energy is equivalent to mass times velocity squared. Thus, by applying the formula, one discovers that your math question is a pointless time-waster.

assuming they both run at the same speed (i.e. same constant speed) out of the runnning blocks, it would be a draw.
