    Welcome to Physics forums.

    Here is a simple trick to remembering how to get distance from velocity.

    How man meters a second is she going and how many seconds is she running for?

    She is running at 3m/s and she is running for 6s

    hope this helps

    What does 3 m/s mean?

    A helpful tactic for you, Ross, is something called dimensional analysis. Dimensional analysis is very useful in checking that your answer is correct, as well as understanding the logic behind the units being used. http://www.alysion.org/dimensional/fun.htm
