it takes a boy 1 hour to mow the front lawn on Saturday morning. The following week he does the same lawn in 0.5 hours. Since he is mowing the same distance, the work is the same. Did the boy use the same amount of power the second time?

In this case His pacing or power has doubled when assuming he is complelting the work at a constant pace.
