Answer:
During the first hour, the water change was 2 feet (or 14 feet)
Step-by-step explanation:
We know that the level of water in a water tank was 16 feet, and that by 8 hours, it was empty. To find the change in the water level per hour, we need to divide 16 by 8.
16 ÷ 8 = 2
Therefore, during the first hour, the water change was 2 feet (or 14 feet)
Hope this helps! :D
