Suppose that the average U.S. household uses 14600 kWh14600 kWh (kilowatt‑hours) of energy in a year. If the average rate of energy consumed by the house was instead diverted to lift a 1470 kg1470 kg car 11.3 m11.3 m into the air, how long would it take?

Using the same rate of energy consumption, how long would it take to lift a loaded Boeing 747 airplane, with a mass of 4.10×105 kg4.10×105 kg , to a cruising altitude of 8.92 km8.92 km ?
