Explanation:
Let's start finding the frequency heard by the bystander due to the moving car. We need to use Doppler effect here:
v is the speed of sound (v = 343 m/s)
So, we have:
Now, the beat frequency heard by the bystander is the combine of the frequencies, it means the difference between them. Therefore the equation is given by:
