Answer:
New depth = -40.75 meters
Explanation:
It should be understood that submersion is a physical process in which height is lost, so that as there is more submersion there is less height, that is, height and submersion are inversely proportional.
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.
In other words, we have ...
Initial Depth = -32.25 meters
Additional depth = -8.5 meters
New depth = -40.75 meters
