Question

A pool 8ft wide and 25ft long was being filled with water.At 10:00 a.M the depth of the water was 2ft, at 3:00 p.M it was 5ft, how full will it be at 10:00 a.M

Answer 1

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.
