A tank contains 1000 liters (L) of a solution consisting of 140 kg of salt dissolved in water. Pure water is pumped into the tank at the rate of 8 L/s, and the mixture-kept uniform by stirring-is pumped out at the same rate. How long will it be until only 10 kg of salt remains in the tank? It will take about seconds. (Round to the nearest second as needed.)
