Answer 2

Explanation:

This is a basic application of propogation of sound in water.

We know that,

Speed of sound in water=1480m/s

Here the time taken for the sound to reach the bottom of the sea is 3s and then the sound to reach back id again 3s.

So in order to get the depth we only need to consider one of the case.

So velocity=distance/time

1480×3=depth

4440m=depth
