Answer:
Let the distance between the ship and the enemy submarine beS.
Speed of sound in water =1450m/s
Time lag between transmission and reception of Sonar waves =77s
In this time lag, sound waves travel a distance which is twice the distance between the ship and the submarine (2S).
Time taken for the sound to reach the submarine =
2
1
×77=38.5s
Distance between the ship and the submarine, S=1450×38.5=55825m=55.8km
