A convertible moves toward you and then passes you; all the while, its loudspeakers are producing a sound. The speed of the car is a constant 8.93 m/s, and the speed of sound is 342 m/s. What is the ratio of the frequency you hear while the car is approaching to the frequency you hear while the car is moving away?
