Explanation:

"To carry a load (1000 newton) a distance of 50 meters a person takes 10 minutes, while another person in the same conditions takes 5 minutes, who does more work? Who has more power?"

Both people exert the same force over the same distance, so they do the same amount of work.

Power = work / time

The second person does the same amount of work but in half the time, so they have twice the power of the first person.
