Question 1112721: Rational Word Problem:
A generator in an electrical power produces 10 MW (megawatts) of electrical power in one hour. A second generator produces 2.5 times as much power as the first, and a third generator produces 50% of the power of the first two combined. How long does it take the 3 generators to produce 210 MW of power?

.
1-st gen produces 10 Mw.


2-nd gen produces 25 Mw.


3-rd gen produces  0.5*(10+25) = 17.5 Mw.


The answer to your question is THIS:   210%2F%2810%2B25%2B17.5%29.

From the PHYSICS point of view, the problem formulation is totally/fatally incorrect and is nonsense.

Because it mix two different conceptions: Power and Energy.
