I need help with this question "A swimmer swims an entire lap, moving from the left end to the right end and back again to the left end in a pool that is 50 meters long". what is the Distance and Displacement?

  1. distance = 2*50 = 100 m
    Since he ends where he started, the displacement is zero m.

    Looks like you need to review this topic a bit more.
