10 kilowatt-hours is enough energy to run a 5,000-watt air conditioner for how long?

Explanation:
Energy, power, and time relate through E = P × t. The air conditioner draws 5 kilowatts, and you have 10 kilowatt-hours of energy available. So the run time is t = E / P = 10 kWh / 5 kW = 2 hours. Two hours matches the energy provided (one hour would use 5 kWh; half an hour about 2.5 kWh; four hours about 20 kWh).
