A swimming pool has a capacity of 2,500,000 liters. Its supply system was set to a constant flow rate of 6,000 liters of water per minute.

The same system was installed in a second swimming pool, with a capacity of 2,750,000 liters, and set to a flow rate, also constant, capable of filling it in a time 20% longer than the time spent to fill the first pool.

The flow rate of the supply system of the second pool, in liters per minute, is
