A man fires a gun and hears its echo after 5s. The man then moves 310 m towards the hill and fires his gun again. If he hears the echo after 3 s, calculate the speed of sound.

A man fires a gun towards a hill and hears its echo after 5 s . He then moves 340 m towards the hill and fires his gun again. This time he hears the echo after 3 s . Calculate the speed of sound.

A boy fires a gun and another boy at a distance of 1020 m hears the sound of firing the gun 3 s after seeing its smoke. Find the speed of sound.

A man stationed between two parallel cliffs fires a gun. He hears the first echo after 1.5 s and the next after 2.5 s . What is the distance between the cliffs and when does the hear the third echo ? Take the speed of sound in air as 340 m//s .

A man fires a gun while standing between two parallel hills. If he hears the first echo after 2 s and the second echo 3 s after the first echo, then calculate the distance between the hills the velocity of sound is 330 m/s.
