Two trucks travel at the same speed. They are far apart on adjacent lanes and approach each other essentially head-on. One driver hears the horn of the other truck at a frequency that is 1.20 times the frequency he hears when the trucks are stationary. The speed of sound is 343 m/s. At what speed is each truck moving?

✔ 最佳答案
They are moving together at 20% the speed of sound, so each is moving at 10% the speed of sound, or 34.3 meters per second.
