Answer:

612 Hz.

Step-by-step explanation:

The frequency of the sound  will be proportionally higher when coming towards you. The increase is related to the speed of the train.

So the frequency will be:  

580 + (580 / 343) * 18.8

=  612 Hz.

This is called the Doppler effect.

-5 = -9 + 4
-5 = -5

They match, so y = x + 4 is the right answer. You can try plugging in the other variables if your still uncertain
