    A train is travelling at 15m/s. It accelerates at 3m/s² for 20 seconds. How far does the train travel in this time?

    Can someone help me please?!

    You should be familiar with the equation:

    s = ut + 1/2at^2 as the user 'wiseguy99' has stated.

    where:

    s = displacement
    u = initial speed
    a = acceleration
    t = time

    We can simply put in the information we have been given to get an answer!

    Hint:

    In your case:

    u = 15
    a = 3
    t = 20

    and 's' is what you are trying to find.
