Answer:
2 ft or 16.4 ft
Explanation:
The problem statement tells you the pool is 2 ft deep at 10:00 am.
__
The depth changes 3 ft in the 5 hours between 10 am and 3 pm, so is changing at the rate of 3/5 ft/hour. In 24 hours, it will change (3/5)(24) = 14.4 ft. Added to the 2 feet of depth at 10 am, the depth at the next instance of 10 am will be 16.4 ft.
