Question

A submarine submerged at a depth of -35.35 meters then dives an additional 8.5 meters. What is the submarine's new depth?

Answer 1

-35.25 - 8.5 = -40.75 meters

Explanation:

When talking about a submersion depth of -32.25 meters, that means the submarine has dropped 32.25 meters.

If we add 8.5 meters of additional submersion to that value, we get:

-32.25 meters + (-8.5 meters) = -32.25 meters - 8.5 meters = -40.75 meters.
