A person watches an ambulance drive by them while emitting a steady sound from its siren. When the ambulance passes the person (switching from moving towards him to moving away from him), the perceived frequency of the sound he receives decreases by 7.23 percent. How fast is the ambulance driving? Give your answer as a positive number. Assume room temperature air (343m/s)
