<h3>Answer:</h3>

7.838 seconds

<h3>Explanation:</h3>

Assuming the sound of sound in seawater is 1531 m/s we can calculate the time taken by the signal to leave the ship and back.
The depth to the bottom is 6000 meters
The sound signal will cover the distance twice, to and fro the bottom to the ship.

In this case;

Time = (2× distance) ÷ velocity

= (2×6000) m ÷ 1531 m/s

= 12000 m ÷ 1531 m/s

= 7.838 s

Therefore, it will take 7.838 s for the sound signal to leave the ship and bounce back off and return to the ship.
