Question

a submarine is cruising at a depth of -50 m relative to the surface of the ocean. it dives to -110 m to avoid sonar detection. what was the submarines change in altitude? m

Explanation:

Step1: Identify initial and final depths

Initial depth: $-50$ m, Final depth: $-110$ m.

Step2: Calculate change in altitude

Change = Final - Initial = $-110 - (-50)$ = $-110 + 50$ = $-60$ m. (Negative indicates descent, magnitude is 60 m change in altitude.)

Answer:

-60
