1 pt 1 Details
A swimming pool is 20 ft wide, 40 ft long, 3 ft deep at the shallow end, and 9 ft deep at
its deepest point. A cross-section is shown in the figure. If the pool is being filled at a rate
of 1.4 $ft^3$/min, how fast is the water level rising when the depth at the deepest point is
5 ft? (Round your answer to five decimal places.)
