Propagation of Sound Waves — Question 6

Given,

Distance between A and B = 1650 m

Speed (V)= 330 m s^-1

time t = ?

V = $\dfrac{\text{Distance (d)}}{\text {Time (t)}}$

Substituting the values, we get,

$330 = \dfrac{1650}{\text t} \\[0.5em] \Rightarrow \text t = \dfrac{1650}{330} \\[0.5em] \Rightarrow \text t = 5 \text { s} \\[0.5em]$

Therefore, the time when B will hear the sound after firing by A = 5 s.
