    1. The problem statement, all variables and given/known data

    A child rides on a pony around a circular track with a radius of 4.5 meters.

    2. Relevant equations

    What is her distance travelled and displacement after she has gone half way around the track?

    3. The attempt at a solution

    Welcome to PF;
    The way we work is that you attempt the problem as far as you can, showing how you are thinking about it, and we help you where you get stuck.

    In this case - think about the geometry, and the definition of "displacement".
    What shape is the track?

    Perhaps start by considering what the distance travelled and displacement would be had the child gone the whole way round the track.
