Answer: To find the number of liters of water in the first pool after x minutes have passed, we can use the formula:
972 + 17x
To find the number of liters of water in the second pool after x minutes have passed, we can use the formula:
44x
Note that both of these formulas assume that the pools are being filled continuously, without any interruptions. If the flow of water into either pool is interrupted at any point, the actual amount of water in the pools may be different from what these formulas predict.
