Given information
From the beat frequency, calculate the velocity of the moving train.
Given values:
The frequency emitted by both trains is 
Hz.
The conductor's frequency on the stationary train is 
Hz.
Speed of sound
Step-by-step explanation
Step 1.
We may note that when two sound waves of different frequencies are released at the same moment, their waves interfere with one another. An oscillating sound with a frequency known as the beat frequency, which is the difference between the frequencies of the sounds, may be heard.
