A Worker Lives at a Distance of 1.32 Km from the Factory. If the Speed of Sound in Air Be 330 M/S, How Much Time Will the Sound of Factory Siren Take to Reach the Worker? - Science

Short Note

A worker lives at a distance of 1.32 km from the factory. If the speed of sound in air be 330 m/s, how much time will the sound of factory siren take to reach the worker?

Solution

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?
