An escalator and an elevator can transport a person from one floor to the next. the escalator does it in 15 s and the elevator takes 10 s. Which does more work on the person? Which has the greater power output?

The escalator does more work and the elevator has a greater power output.

Explanation:

The escalator does more work on the person because it is carrying them up. It also gives the person a chance to walk up the escalator making it a little more challenging than using just an elevator. The elevator has a greater power output because it can transport a person from one floor to another in just 10 seconds where as the escalator can do it in 15.
