Manipulate: Rearrange your equation to solve for the velocity of the source.

vs = v-cfs/f

Practice: The speed of sound at sea level is normally about 340 m/s. A car honks its horn as it drives toward an observer. The frequency of the horn is 800 Hz, but the observer hears an 860-Hz pitch.

What is the velocity of the car?
