Question

calculate the distance between source and obstacle if an echo is heard after 3s. given velocity of sound in air is 330m/s.​

Answer 1

time - 3s

v - 330m/s

2d =v/t

I THINK YOU CAN FURTHER SOLVE BY THIS FORMULA

Answer 2

Distance = speed * time
Given speed = 330m/s
Given time = 3s
Distance = 330*3
= 990 metres
Distance for echo = d/2
= 990/2
=495 metres
The distance between the source and obstacle is 495 metres .
