    The question has given you enough info to sketch the wave profile the various time.

    At t = 1.5 s, it is 1/4 of the period.

    It will be a horizontal line where every part of the string is at the equilibrium position.

    At t = 3.0 s, it is half a period.

    The wave profile is inverted.

    There is an animation known as Standing Waves Interactive in the following website where you can watch how the standing wave changes the profile as time changes.

    The period of the standing wave is 1.0 s.
