Answer:
The constant rate of change is 2 feet every hour.
Step-by-step explanation:
Since the level of the water was at 10 feet at 2 pm, and the water at 6 pm was at 2 feet, the water level dropped 8 feet in 4 hours.
With this information we can create the ratio 4:8 and when you simplify the ratio down to 1, you get 1:2
1 Representing 1 hour
2 Representing 2 feet
Every hour, the water level drops 2 feet.
