Example 4 The jet engines on a Boeing 757 must develop a certain amount of power to propel the airplane through the air with a speed of 320 km/h at a cruising altitude of 5,000 m. By what percent must the power be increased if the same airplane were to maintain its 320 km/h flight speed at sea level?
