Question

What is the final elevation if a fish starts at -9 meters and changes its elevation by -11

Answer 1

Final elevation = -20m

Step-by-step explanation:

Start point = -9 meters

Change in elevation = -11

Final elevation = Start point + Change in elevation

Final elevation = -9 m + (-11)m

Final elevation = = -9m -11m

Final elevation = -20m

This indicates it is 20meters below sea level using 0 as reference point.
