Power Needed!!

A fully loaded, slow-moving freight elevator has a cab with total mass of 1200 kg, which is required to travel upward 54 m in 3.0 min, starting and ending at rest. The elevator's counter-weight has a mass of only 950 kg, and so the elevator motor must help. What average power (in Watts) must be generated by the motor to move the elevator?
