Given that -> pool is rectangular
-> it has uniform depth

Target question =>How long will it take to fill the pool with water?

Time to fill pool = volume of pool * rate of water influx
Where volume of rectangular pool = length * width * height
Time taken = (lwh) influx rate

Statement 1 => Water will be pumped at the rate of 240 gallons per hour (1 cubic foot = 7.5 gallons)
If 1 cubic foot = 7.5gallon then
x cubic foot = 240/7.5 = 32 cubic foot per hour
Influx rate = 32 cubic foot per hour
The length, width, and height are unknown so the time taken cannot be evaluated. Statement 1 is NOT SUFFICIENT

Statement 2=> The pool is 60 feet long and 25 feet wide
Length = 60 ft, width = 25 ft; height and influx rate is unknown. Therefore, the time taken cannot be evaluated. Statement 2 is NOT SUFFICIENT

Combining both statements together =>
From statement 1 => influx rate = 32 cubic foot per hour
From statement 2 => length = 60ft and width = 25ft
Height still remains unknown and time taken cannot be evaluated. Both statements together are NOT SUFFICIENT

Answer = E
