A train is moving parallel to a highway with a constant speed of 20 m/s. A car is traveling with a speed of 40.0 m/s. The car's horn sound at a frequency of 510 Hz, and the train whistle sounds at a frequency of 320 Hz. When the car is behind the train, what frequency does an occupant of the car observe for the train whistle?
