A girl is snorkeling 1meter below sea level and then dives down another 0.5 meters. How far below sea level is the girl?
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 :)
