Hi friend

Your answer
---------------------

Mass = m = 62 kg

Number of steps = 65

Time = t = 12 seconds

Height of each step = 20 cm

Total height climbed by the person = (65 × 20)/100 m = 13 m

So,
-------

Power = p = work done (w)/ Time taken (t)

P = w/t

P = mgh/t. [ Because w = mgh]

P = (62×10×13)/12

P = 671.66 Watt

HOPE IT HELPS
