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.
1.) Plug x and y to the formula:
4(2) + 1/3(3)^2
2.) Simplify
8 + 1/3(9)
= 8 + 3
= 11
Hope this helped!!!
