Does anyone know how to answer this question?

Question: How do i determine power generated by an applied force if it takes 9.0 s to push the box up the ramp.
I am given
mass=2.0kg
height of ramp= 2.7m
length of ramp= 5.3m
angle= 30*
constant force= 12N
What should i do I am stuck ! tell me what equation i should use. Please

First calculate the work done in pushing the box the distance you want.
W=Force * distance

then remember that power is simply work done divided by time.
 
So basically i just divide the work by 9 seconds and i get j/s as its unit?

J s^-1 are indeed the units of power :).
