b) A man standing at the start position of a car racing track fires a gun. The other man standing at the end of the track hears the sound after 4 s. If the speed of sound in air is 330 m/s, find the distance between these two men. Will this distance be the same if the race is for submarines and the gun is fired underwater?

Answer:
speed of sound,s=330m/s
Time,t=4s
Distance=speed×time
Distance=330×4
distance=1320m
No, because the speed of sound is different in different media(solid, liquid or gas).
