A car is on a road parallel to a railroad track and right beside it. The car is travelling east
at 30.0 m/s while a train travelling west at 50.0 m/s is approaching it. If the car honks its
horn at a frequency of 1.00 kHz, what is the wavelength of the sound perceived by a person
riding in the train?
The answer is 0.313, can somebody explain to me how to get 0.313 because I keep getting 0.273m as a wavelength...
