a man carries a load of 50 kg to a height of 15 m in 5 minutes. calculate the work load?

The work is
W = M g H =
(50 kg)*(9.8 m/s^2)*(15 m) = 7350 Joules
Divide that by 300 seconds for the average power in Watts.
I have never heard of power referred to as "work load", but assume that is what they mean.
