How much power is needed for a 44 kg person to climb 12 flights of stairs that each have a height of 2 meters, in a time of 15 seconds?

2. Relevant equations

P=W/T

3. The attempt at a solution

answer from the teacher is 690 W. i remember doing the something like this in class but i dont remember exactly what all to do. wouldnt you multiply 12 by 2 so its total distance then multiply it by the 15 for the total time? or is that just time in general, the total? then put it into the power equation? i know youre supposed to convert the mass into N but thats it. im so lost please help me.

thank you!
