A boy fires a gun and another boy at a distance of 1360 m hears the sound of firing the gun 4 s after its smoke is seen. Find 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 boy fires a gun and another boy at a distance hears the sound of fire 2.5 s after seeing the flash. If speed of sound in air is 340 m s^(-1) , find the distance between the boys.

An observer A fires a gun and another observer B at a distance 1650 m away from A hears its sound. If the speed of sound is 330 m/s, Find the time when B will hear the sound after firing by A.

An observer A fires a gun and another observer B at a distance 1650 m away from A hears its sound. If the speed of sound is 330 m s^(-1) , find the time when B will hear the sound after firing by A.

A person is standing at the sea shore. An observer on the ship which is anchored in between a vertical cliff and the person on the shore fires a gun. the person on the shore hears two sounds, 2 seconds and 3 seconds after seeing the smoke of the fired gun. If the speed of sound in the air is 320 m s^(-1) -, then calculate : the distance between the observer on the ship and the person on the shore.

A boy on a hill A fires a gun. Another boy on hill B hears the sound after 4 s. If the speed of sound is 330 m s^(-1) , find the distance between the two hills.

A person standing at a distance x in front of a cliff fires a gun. Another person B standing behind the person A at distance y from the cliff hears two sounds of the fired shot after 2s and 3s respectively. Calculate x and y (take speed of sound 320 m s^(-1) ).

A car is traveling on a straight level track with a uniform speed of 25 m/s. When the car is moving away from a gun at the same level at a distance of 1500 m the gun is fired at an angle of 45^(@) . Find the distance of the car (kilometers) from the gun when it is hit.

An observer sitting in line of two tanks, watches the flashes of two tanks firing at each other at the same time, but he hears the sounds of two shots 2 s and 3.5 s after seeing the flashes. If distance between the two tanks is 510 m, find the speed of sound.
