If a runner's power is 133 W as she runs, how much work is done by the runner in 6 minutes? Round to the nearest whole number.

The power in watts is the energy in Joules used per second. This is:

P [W] = E[J] / t[s]

Solving for Energy:

E = P*t

We must convert the time to seconds knowing that 1 min = 60 s:

t = 6 min × 60 = 360 s

Finally:

E = P*t

E = 133 W * 360 s

E = 47880 J

real, smaller and upside-down.   so the answer should be b.

energy can be converted from one form to another, but it cannot be created or destroyed in ordinary chemical or physical means. do not understand what you are asking but hope this
