As you stand by the side of the road, a acr approaches you at a constant speed, sounding its horn, and you hear a frequency of 80.0 Hz. After the car goes by, you hear a frequency of 60.0 Hz. What is the speed of the car? The speed of sound in the air is 343 m/s. The answer shoudl be 49m/s, I am more confused on how to solve algebraically. I attached a photo of how far I made it lol.
