Question

Assuming that the average speed of sound waves in water is 1500 meters per second, determine the water depth if a signal sent out by an echo sounder on a research vessel requires 6 seconds to strike bottom and return to the recorder aboard the ship.

Answer 1

4500 meters

Step-by-step explanation:

You only need the distance from the vessel to bottom.

Since it takes 6 seconds to go to the bottom and back, you can divide 6 by 2.

3 seconds to reach the bottom.

1500 x 3 = 4500 meters
