Crane A has 2.0 as much power as Crane B.
If Crane B can do 9492 Joules of work in 12.492 minutes, how many Joules of work can Crane A do in 12.492 minutes?

Does crane A and B have anything in common?

They are both using rope and pulley systems to lift a load from a truck to the top of a building

something is missing.

that's all that was given in the problem

P(A) = W(A)/t = 9492/12.492•60 = 12.66 W
P(B) = P(A)/2 = 6.33 W
W(B) = P(B) •t = 6.33•12.492•60 = 4946 W
