We have to calculate the time taken by the sound wave to reach the observer.
Given: Velocity of sound ν = 330 m/s
Distance between the observer and the source d = 1,320 m.
We know, `"Time" = "Distance"/"Speed"`
Therefore , time taken by the sound wave to reach the observer is = `1320/330` s
= 4 s
So , the time taken is 4 s . 

  Is there an error in this question or solution?
