To find the water level at the end of summer, we start with the initial water level, which is 112 meters below sea level, and then we account for the additional drop of 213 meters during the summer.
We can represent the water level below sea level mathematically:
- Initial water level: -112 meters (below sea level)
- Additional drop during summer: -213 meters (below sea level)
Now we add these two values together to find the final water level:
\[ -112 + (-213) = -112 - 213 = -325 \text{ meters} \]
Thus, the water level at the end of summer is 325 meters below sea level.
The water level is 325 meters from sea level.
