Question

A SONAR device fitted in a submarine receives an echo 4 seconds
later the signal is transmitted towards another submarine 3060m
away Find the speed of sound in water

Mohammed Javed · Answer

d = v * t / 2
2d = v * t2 ( 3060 ) = v * 46120 / 4 = v1530 = v

A SONAR device fitted in a submarine receives an echo 4 seconds later the signal is transmitted towards another submarine 3060m away. Find the speed of sound in water.
