To find out how long it would take for a 60 W lamp to consume 30.24 kilowatt-hours (kWh) of power, we first convert the power consumption into the same units. 60 W is equal to 0.06 kW. Then, we use the formula for energy consumption: Energy (kWh) = Power (kW) × Time (hours). Rearranging this formula to solve for time gives us Time = Energy / Power. Plugging in the numbers gives us Time = 30.24 kWh / 0.06 kW = 504 hours. Since there are 24 hours in a day, 504 hours is equal to 21 days, which is approximately 3 weeks.
