How much time does it take to lift the piano?

Monday, December 15th, 2008

A 1.40 102 kg piano is being lifted at a steady speed from ground level straight up to an apartment 12.0 m above the ground. The crane that is doing the lifting produces a steady power of 4.00 102 W. How much time does it take to lift the piano?
