    There's not enough info as the problem is stated. I think you left something out.

    Doesn't a graph go with it?

    The graph I saw for this exact problem has two lines and you're supposed to find where they will intersect.

    Tank T has points at (0,900) and (3,750)

    Tank W has points at (0,300) and (3,375)

    Find the equations of the two lines using these data points, set them equal and solve.

    I will give you a start. Tank T has line equation

    Find the other and you're on your way.
