FA#5-Television, part II

To solve this question, we must figure out how many years it takes the galaxy to make one rotation (~220,000,000 years). Next we must convert this number to hours (1 years = 8,765.81277 hours). We have a total of 1,928,478,809,565 hours. Now we have to take Turn Off Your T.V. week into account. At a rate of 1 week = 168 hours, 220,000,000 weeks = 36,960,000,000 hours. Subtract our Turn Off Your T.V. week hours from the total (1,891,518,809,565 hours). Multiply the number of hours by the total kilowatts/hour the televisions of the U.S.A. consume (106,443,900*1,891,518,809,565=2.01340639E20). One step left; convert kw to watts (2.01E23). FA#5 = 23.
