Agood way to measure your power is
a. to walk on a balance beam
b. to jog a mile to loosen up
c. to stretch joints and muscles regularly
d. to run 10 flights of stairs in several minutes

D

Explanation: Power = W/t = (F *s)/t

Where: W = work

F = Force

s = Distance

t = Time

To run indicates motion, which implies force. "F"

10flights indicates the distance covered "s"

Over a period of several minutes indicating time "t"

Since we know the formulae for Power = W/t = (F *s)/t

All parameters are accounted for in the statement.

Therefore, the answer to the question is D.
