To calculate how far below sea level the girl is, you simply need to add 1 meter to 0.5 meters. This gives you the answer of 1.5 meters below sea level. (not sure what I can add to this answer)

Answer:

She is 1.5 meters below the sea level


Explanation:

The sea level is indicated by the number 0

What's above the sea level is indicated by +ve numbers

What's below the sea level is indicated by -ve numbers


We know that:

originally, her depth was 1 meter below the sea level

This means that her original depth is -1


Now, she dives an extra 0.5 meters, to get her final depth, we would add -0.5 to the original -1 meters


This means that:

her depth = -1 + (-0.5) = -1.5 meters

where the negative sign indicates that she is below the sea level


Hope this helps :)
