you measure the depth to the bottom with a lead line and find out the bottom is 6000 meters deep. How many seconds would it take for a seconds would it take for a sound signal to leave the ship, bounce off the bottom and return to ship? Show your work

7.838 seconds

Explanation: 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. Time is calculated by dividing the distance by the velocity or speed.

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.
