Question

A naval submarine was operating 310 feet below the surface of the ocean. To pass above an underwater mountain or seamount, it rose 165 feet.
What is the position of the submarine relative to the surface of the ocean now?

Answer 1

Answer:

145 ft below the surface of the ocean

Step-by-step explanation:

Simply subtract 165 feet from 310 feet because the depth is decreasing.  It can also help to sketch out the submarine to better visualize it :)
