A stationary police car emits a sound of frequency 1232 Hz. The sound wave bounces off a car on the
highway, then returns with a frequency of 1383 Hz. The police car is right next to the highway, so the
moving car may either be moving directly toward or away from it. Determine the speed (in m/s) of the
car. Treat the speed of sound to be 335 m/s.
Express your answer in 2 decimal places.
