Interesting. As a position relative to the surface, the value is -550.
But, as you say, the depth is indeed 550 ft. "Depth" carries with it an implied negative value.
I'd check to see just how they want you to interpret positive and negative quantities.
A submarine at the surface dives 375 ft and then another 175 ft. Express the final depth as an integer.
A. –525 ft
B. –550 ft
C. 550 ft
D. 525 ft
C?
