An ambulance passes by a stationary observer releasing its siren at a frequency of 479Hz. The difference between the frequency observed by the observer as the car was approaching and with when the ambulance was moving away was 62Hz. How fast is the ambulance moving? Assume the speed of sound is 339m/s
