A man stands in front of a hillock and fires a gun. He hears an echo after 1.5s. The distance of the hillock from the man is (velocity of sound in air is `330ms^-1`)

A man stands in front of a hillock and fires a gun. He hears an echo after 1.5 sec . The distance of the hillock from the man is (velocity of sound in air is 330 m/s )

A person in front of a hill at a distance 337.5 m fires a bullet. If he hears an echo after 2.25 s, then the velocity of sound will be

The minimum distance to hear an echo is (Taking the velocity of sound in air to be 330 m s^(-1) )

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 man standing on a cliff claps his hand hears its echo after 1 sec . If sound is reflected from another mountain and velocity of sound in air is 340 m / sec . Then the distance between the man and reflection point is

A person standing between two parallel hills fires a gun. He hears the first echo after 1.5 sec and the second after 2.5 sec. If the speed of sound in air is 332 m/s. Then find the time (in sec) when he hear the third echo?
