The water level of a river is below normal levels. It's water level is at 1 1/2 meter below sea level. During the summer
months, the water level decreases even further, reaching 2 1/4 meters below sea level. The low water level has caused concerns among boaters and fishermen, as it affects their ability to navigate and access certain areas of the river. It has also led to changes in wildlife behavior, as some species are unable to find sufficient food and shelter in the shallow waters. Efforts are being made to monitor and analyze the reasons behind the low water levels, such as drought conditions or upstream water usage. Additionally, measures to mitigate the impact on the river's ecosystem are being considered, such as implementing water conservation measures and restoring vegetation along the riverbanks.
To calculate the water level of the river during the summer, let's assume that the normal sea level is 0 meters.
Step 1: Convert the water level below sea level to a positive value.
The water level is currently at 1 1/2 meters below sea level, which can be written as -1 1/2 meters. To convert this to a positive value, we can add 1 1/2 meters to it.
-1 1/2 meters + 1 1/2 meters = -1/2 meters
Step 2: Convert the negative value to a positive value.
Since we are measuring the water level below sea level, a negative value indicates that the water level is below sea level. To convert it to a positive value that indicates how far below sea level it is, we can multiply it by -1.
-1/2 meters × -1 = 1/2 meters
So, during the summer, the water level of the river is 1/2 meter below normal sea level.
