Electrical physics question

I'm not usually an idiot when it comes to a question like this but I don't understand why the answer to this question is .2kW-h. How many kilowatt hours of energy does it require to operate a 1200 watt hair dryer for 10min?I will name my first born after your gspot name if you can help. :P Electrical physics question
About 0.2 I guessElectrical physics question
1200 watts= 1.2 KW10 min = 1/6 h 1.2/6 = 0.2 =0.2 Kwh
1200 watt hairdryer takes 1.2kwh to run for one hour10 minutes goes into an hour 6 times1.2 divided by 6 = 0.2
Heh, maybe I am an idiot. :P Thanks though!
