The power that the runner is exerting while running is 814.1 Watts.
In this question, we need to find the power (in watts) that the runner is exerting while running.
Power is defined as the quotient between the used energy and the time in which that energy is used.
So here we have:
[tex]P = \frac{700 Kcal}{1h}[/tex]
And we know that 1 kcal/h = 1.163 watts
Then we can rewrite:
[tex]P = \frac{700 Kcal}{1h} = 700 Kcal/h = 700*(1.163 W) = 814.1 W[/tex]
