Hi ArtisticApple5172.
Welcome in the Zone!
Given P = E/∆t, you just have to divide the energy E by the time ∆t. But time has to be converted in hours because "hour" appear in the unit kWh (kilowatt-hour). The unit of your answer will be kW, so you will have to multiply it by 1000 to transform it in Watts. That's it!
