A man standing in front of a vertical cliff fires a gun. He hears the echo after 3.5 seconds. On moving closer to the cliff by 84 m, he hears the echo after 3 seconds. Calculate the distance of the cliff from the initial position of the man.

A man standing in front of a vertical cliff fires a gun. He hears the echo after 3 s. On moving closer to the cliff by 82-5 m, he fires again and hears the echo after 2.5 s. Find : the distance of the cliff from the initial position of the man,

A man standing in front of a vertical cliff fires a gun. He hears the echo after 3 s. On moving closer to the cliff by 82.5 m, he fires again and hears the echo after 2.5 s. Find : the speed of sound.

A person standing between two vertical cliffs and 480 m from the nearest cliff shouts. He hears the first echo after 3 s and the second echo 2 s later. Calculate : The distance of the other cliff from the person.

A man standing in front of a wall produces a sound and hears an echo after 3 s. He walks .X. m away from the wall and produces the same sound. Now he hears an echo after 5.25 s. Calculate distance he walked away from the wall. (Speed of sound in air is 340 m/s)

A person standing between two vertical cliffs and 640 m away from the nearest cliff, produces sound. He hears the first echo after 4 s and the second echo 3 s later. Calculate : the distance between the cliffs

A person standing between two vertical cliffs and 480 m from the nearest cliff shouts. He hears the first echo after 3 s and the second echo 2 s later. Calculate : The speed of sound.

A person clapped his hands near a cliff and heard the echo after 2 s. what is the distance of the cliff from the person if the speed of the sound. v is taken as 346 ms^(-1) ?
