Math question: A new coal-burning power plant can generate 1 gigawatt (billion watts) of power. Burning 1 kilogram of coal yields about 450 kilowatt-hours of energy.

a) How much energy, in kilowatt-hours, can the plant generate each month?

b) How much coal, in kilograms, is needed by this power plant each month?

c) If a typical home uses 1000 kilowatt-hours per month, how many homes can this power plant supply with energy?
 
Does the plant generate the 1 GW of power in a day? In a month? Hourly? (Without knowing the time-period, I don't see any way to convert the "1 GW" into "kW-hours per month", is why I ask.)

When you reply, please include everything you have tried so far, so the tutors can see where you are stuck. Thank you.

Coal-burning plant

Unfortunately, the book is not specific.
I believe that is why I'm stuck.

I was able to come up with 1.62x10 to the eight power, (162,000,000), for the amount of coal burned, which is correct, according to the book.

But, nowhere near the720,000,000 Kwh per month.

720,00 homes.[/quote]

I think we are supposed to assume it is per month; although the book does not say so specifically.
