Question: An air conditioner running for eight hours would consume 7.2 kilowatts. How many kilowatts would the air conditioner consume if it was used for 6 hours a day for 5 days? Think carefully first, then make a decision:
The air conditioner consumes 7.2 / 8 = 0.9 kilowatt per hour. So, in 6 hours, it will consume 0.9 kilowatts per hour * 6 hours = 5.4 kilowatts. In 5 days, its total consumption is 5.4 kilowatts * 5 = 27 kilowatts. So the answer is 27.
