A submarine is cruising at a depth of
\[-50\,\text{m}\] relative to the surface of the ocean. It dives to
\[-110\,\text{m}\] to avoid sonar detection.
What was the submarine's change in altitude?
To find the submarine's change in altitude, we need to find the difference between its initial depth and its final depth.
The initial depth was \(-50\,\text{m}\), and the final depth was \(-110\,\text{m}\).
To find the change in altitude, we subtract the initial depth from the final depth:
\[-110\,\text{m} - (-50\,\text{m}) = -110\,\text{m} + 50\,\text{m} = -60\,\text{m}\]
Therefore, the submarine's change in altitude is \(-60\,\text{m}\).
