Question

A man claps his hand near a mountain and hears the echo after 4 seconds.If the speed of sound under these conditions be 330 m/s,what is the distance of mountain from the man?

Answer 1

t = 4seconds

It is the time taken by the sound to travel to the mountain and return back to the man after striking the mountain.

The time taken by sound to go to the mountain = 2seconds

Speed of sound = 330m/s

Distance = Speed×time

=> 330×2

=> 660m

The distance of mountain from the man = 660m

Cheers!
