Use the diagram to answer the question.

In the figure above, suppose that waves from the ship are sent down and reflected back up by the sunken ship. If it takes two seconds for the waves to travel from their source to the sunken ship and back, what is the depth of the sunken ship? (Assume that the speed of the waves is 1,500 m/s.)
2,500 m
3,000 m
1,500 m
750 m

The depth of the sunken ship can be calculated using the formula:

Depth = (Speed of wave x Time taken for round trip) / 2

Substituting the given values, we get:

Depth = (1500 m/s x 2 s) / 2
Depth = 1500 m

Therefore, the depth of the sunken ship is 1500 meters. Answer is: 1,500 m.
