We are actually looking for the power out of the motor. . . .

Now here is a test. It is two miles to grandma's house. One mile up the hill and one mile down the hill. My old car can only go 30 mph up the hill. How fast must I come down the hill to average 60 miles an hour?

I realize "power" is the proper terminology used by engineers as opposed to work, and I promise to be more careful in my explanations.

P.S. Average speed is based on time.
