Answer:
The girl is 2.5 meters below sea level
Step-by-step explanation:
We are told in the question that:
A girl is snorkeling 1 meter below sea level
Hence, her elevation in meters below the sea level = -1m
We are told in the question that:
She then dives down another 1.5 meters
Once again: Her elevation in meters below the sea level = -1.5m
How far below sea level is the girl?
This is calculated as:
-1 m + -1.5m
= -1m - 1.5m
= -2.5m
Therefore, the girl is 2.5 meters below sea level
