A landowner wanted to determine the change in the water levels of his pond over time. First, he filled the pond to a water level of five feet After two weeks, the water level was at 3.4 feet.

Answer 1

To determine the change in water levels over time, you need to calculate the difference between the initial water level and the final water level.

Initial water level: 5 feet
Final water level: 3.4 feet

Change in water level = Final water level - Initial water level
Change in water level = 3.4 feet - 5 feet
Change in water level = -1.6 feet

Thus, the water level in the pond decreased by 1.6 feet over the two-week period.
