Pendulum equations - HELP review work, out sick

    Pendulum equations - HELP!! review work, out sick

    1. The problem statement, all variables and given/known data
    What is the period ofa pendulum which makes thirty oscillations in 75.0 seconds?

    2. Relevant equations
    T = [l]\frac{}{}[/f]

    This is what I need!

    3. The attempt at a solution
    t=[75]\frac{}{}[/30] = 2.5

    I was out for an entire week, and the teacher sent home a sheet full of questions like this. I don't have any of the equations though. Help please!?

    The period is the time it takes a pendulum to complete one oscillation. If it makes 30 in 75 seconds how long will it take to do one?
