Power for raising on platform

I could derive inverse relation between power and time but it's Physics Olympaid Preselection test question so,i'm not too sure whether this logic is sufficient on this question.
Q)Does the power needed to raise a box onto a platform depend on how fast it
is raised? Explain.
