Answer:

D. a measure of how fast a machine performs work​

Explanation:

Power can be defined as the energy required to do work per unit time.

Mathematically, it is given by the formula;

[tex] Power = \frac {Energy}{time} [/tex]

Hence, the best description of power is that, it is a measure of how fast a machine performs work.

This can be calculated by using the mathematical expression below;

[tex] Power = \frac {Work done}{Time} [/tex]

But we know that, [tex] Workdone = force * distance [/tex]
