m=60kg
distance= number of steps* distance covered in one step
=10*0.5=5m
t=30 s
g=10m/s^2
work done= change in potential energy
=mass*g*height
power= work/time
power= mgh/time
(60*10*5)/ 30 sec
power=100 joules/second
hope this helps...

Time:30sec.
Total distance:10×0.5=5
Time taken:30sec
Power=work÷time
P=mgh÷t
P=60×10×5÷30
P=600×5÷30
P=20×5=100w
Therefore,the power used was 100w (or) 1kw
