We have been given that the submarine’s depth was twice the depth of the shark. This means that depth of submarine would be
.
We have been given that a submarine was 144 feet below sea level, so submarine's elevation would be
.We can represent this information in an equation as:

To find shark's position, we need to solve for x.


Therefore,
feet represents shark's elevation, which represents that shark is 72 feet below sea level.
