Two racecars start a race at the same place and finish the race in a perfect tie. Prove there was at least one moment during the race when both cars were going at exactly the same speed. (HINT: Let f(t) represent the location of the first car at time t, and let g(t) represent the location of the second car at time t. Let h(t) think the function h(t) merits some serious consideration.) f(t) – g(t). I
