A commercial flight from New York to Somewhere flies 3000 km from airport to airport. One day, due to strong headwinds the flight's average speed is decreased by 150 km/h and the flight takes an
additional hour, compared to its normal flight time. Create an expression to determine the average
speed of this commercial jet without headwinds.
