    [SOLVED] Speed, acceleration time and distance

    1. The problem statement, all variables and given/known data
    A car is travelling at 4.2m/s and accelerates at 1.1ms (squared).

    In the time of 7.4 seconds how far has the car travelled?


    2. Relevant equations

    Not sure.

    3. The attempt at a solution

    I can't work it out so I'd really appreciate a little help, I know I sound dumb but i need it!
