An empty rectangular swimming pool has uniform depth. How long will it take to fill the pool with water?
(1) Water will be pumped in at the rate of 240 gallons per hour (1 cubic foot = 7.5 gallons)
(2) The pool is 60 feet long and 25 feet wide

Question: Time to fill the rectangular swimming pool = Volume of Pool/Pumping rate = L*B*H/Pumping rate = ?
Statement 1: Water will be pumped in at the rate of 240 gallons per hour
The volume can't be calculated as the volume of pool is also required to calculate time of pumping hence
NOT SUFFICIENT
Statement 2: The pool is 60 feet long and 25 feet wide
The depth of pool is unknown alongwith that the rate of pumping also is unknown hence
NOT SUFFICIENT
Combining the two statements
Depth of pool to be filled is still unknown so the volume can't be calculated hence time of filling pool can't be calculated hence
NOT SUFFICIENT
Answer: Option E

(1) Water will be pumped in at the rate of 240 gallons per hour (1 cubic foot = 7.5 gallons)
(2) The pool is 60 feet long and 25 feet wide
Ans - Time required will be = Total pool volume / Rate per unit (speed of filling.)
V = L*B*H and Rate =volume filled/time both are needed to answer the question.
1. Water will be pumped in at the rate of 240 gallons per hour (1 cubic foot = 7.5 gallons) - Rate is given but height is not. Not sufficient.
2. The pool is 60 feet long and 25 feet wide - still depth is not given. Not sufficient.
1+2 - still depth is missing. Hence ans is E.
KUDOS!!
