Power = Δw/Δt
or
Power = Δe/Δt

*in this case you are only given the force, distance and the time. I would solve for the work and then plug that value into the first power formula listed.

W = F * distance
w = 100 * 5
W = 500
so.......

Power = Δw/Δt
P = 500/4.00
P = 125 <-- that is the answer

hope this helps :)
