The water level of a river is below normal levels. Its water level is at 112
meters below sea level. During the summer, the river drops another 213
meters below sea level. What is the water level at the end of summer? Remember, the elevation is below sea level. Account for this in your answer.
The initial water level of the river is 112 meters below sea level. During the summer, it drops another 213 meters below sea level.
To find the total drop in water level, we add the initial drop to the drop during the summer: 112 meters + 213 meters = 325 meters.
Therefore, at the end of summer, the water level of the river is 325 meters below sea level.
To find the water level at the end of summer, we need to add the initial water level below sea level (-112 meters) to the drop in water level during the summer (-213 meters).
-112 meters + (-213 meters) = -112 meters - 213 meters = -325 meters
Therefore, the water level at the end of summer is 325 meters below sea level.
