Suppose you bake a potato in a toaster oven that uses 1.2 kW. The oven is turned on for 25 minutes. How many kilowatt hours did it use?

0.3kilowatts hours

Explanation:

If you bake a potato in a toaster oven that uses 1.2 kW and oven turned on for 25minutes, to get the amount in kilowatt hour, we will need to convert minutes to hour first

60minutes = 1hr

25minutes = x

60x = 25

x = 25/60 hr

x =

Multiply the time in hr with the power

Amount of kWhr used = 1.2 * 25/60

Amount of kWhr used = 30/60

Amount of kWhr used  = 0.3kilowatts hours

Hence it used 0.3kilowatts hours
