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

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 soldier fires a bullet towards a fort-wall and hears the first echo after 2s. He moves a distance of 85m towards the wall, fires a bullet and hears the echo after 1.5 s. The velocity of sound is

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 man standing at a certain distance blows a horn towards a big wall. He hears the echo after 2s, if the velocity of sound in air is 340 m/s, then the distance between the man and the wall is

A man stands at a distance of 250 m from a wall. He shoots a rifle and hears the echo after 1.3 seconds. Calculate the velocity of sound.

A man standing at a point on the line joining the feet of two cliffs fires a bullet . If he hears the 1^(st) echo after 4 seconds and the next after 6 seconds , then what is the distance between the two cliffs ? (Take the velocity of sound in air as 330 m s^(-1) )

The minimum distance required to hear an echo is ________ part of the magnitude of the velocity of sound in air.

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.
