    A car moving at 35 m/s approaches a stationary whistle that emits a 220 Hz sound. The speed of sound is 343 m/s. What is the speed of the sound relative to the driver of the car?

    Again, we don't do homework for you and you should post these kind of questions (with your work and a specific question about what you are having trouble with) on the homework help part of the site.

    What are your thoughts? The question is not as complicated as it might seem at first!

    Sound travels the same speed in the air no matter its hertz or frequcncy so the sound relative to the car would be 308m/s if it is traveling away from it
