Dawn is going scuba diving. Which situation would be modeled by a positive number?

Question

on the dive boat deck
at the water line
underwater near a reef
on the ocean floor

Answer 1

The situation that would be modeled by a positive number is "on the dive boat deck." This location is above sea level, and positive numbers are typically used to represent heights or elevations above a reference point, which in this case is the water's surface.

In contrast, being at the water line, underwater near a reef, or on the ocean floor would all be modeled by negative numbers since those locations are below sea level.
