Answer:
Both of you have done the same work. But you generated more power.
Step-by-step explanation:
Since you and your friend have the same mass, your work done by overcoming gravity is the same. But since you done the same amount of work using less time than your friend, by P=W/t (P represents your power, W is the work done, t is the time), you have less time, so you have a greater power.
