Need help on this one

  1. Sep 26, 2006 #1
    Two runners start simultaneously from the same point on a circular 200-m track and run in the same direction. One runs at constand speed of 6.20 m/s and the other at a constant speed of 5.50 m/s. When will the fast one overtake("lap") the slower one and how far from the starting point will each have run?

    please help thx.

    Show us how you think you should set up the algebra to solve this. Think of it in terms of some number of 200m laps plus a little extra. The faster runner runs one more lap than the slower runner, plus that same extra fraction of a lap (which could be zero if the numbers were set up that way).
