Using the formula for power, which is Power = Work/Time, you can calculate the work done by the secretary (Work = Force x Distance). The force the secretary is exerting is equal to her weight (mass x gravity), and the speed is distance over time. Once you calculate the work done, you can divide it by the time to find the average power supplied.
