An ambulance with a siren emitting a whine at 1,190 Hz overtakes and passes a cyclist pedaling a bike at 2.1 m/s. After being passed, the cyclist hears a frequency of 971 Hz. How fast is the ambulance moving? (The frequency 1,190 Hz before the ambulance overtakes the cyclist is the frequency observed by the cyclist.)
