Power to lift* a piano

A piano of mass 200 kg is lifted vertically by a 0.5 hp motor. Given that 746 watt = 1 hp,

how long will it take the motor to lift the piano to an apartment that is 20 m above the

ground?

Not really sure how to start this question, so any explanation would be greatly appreciated.
