SUMMARY
The discussion centers on calculating the speed of Train B using the Doppler effect, given that both trains emit a whistle at a frequency of 246 Hz. Train A is stationary, while Train B approaches the station, resulting in 5.39 beats per second detected by the conductor of Train B. Using the formula f' = f (v + 0 / v - vs) and the speed of sound at 340 m/s, the speed of Train B can be determined through the observed beat frequency.
