Pa submarine submerged at a depth of -35.25 meters dives an additional 8.5 meters. what is the new depth of the submarine?

New depth = Original depth + additional depth

                   = - 35.25 + (- 8.5)

                   = - 35.25 - 8.5

                   = - 43.75

Hence, new depth of the submarine is - 43.75 meters.
