Question

A plane took a Navy Seal to a height of 10,000 feet above sea level. The Navy Seal jumped out of the plane and parachuted into the sea 10,000 feet down. Once in the sea, the Navy Seal dove 100 feet down before rising back up 25 feet. What is the Navy Seal's current depth?

Answer 1

It will be 5 feet of depth

Answer 2

75 feet below sea level

The 10,000 feet up and down cancel each other out. So all that matters is the 100 feet down and the 25 feet back up. So that's 75 feet below sea level.
