The liquid inside each tank is kept well stirred. A brine solution with a concentration of 0.2Kg;L of salt flows into tank A at a rate of 6L/min. The (diluted) solution flows out of the system from tank A at 4L.min and from tank B at 2L/min. If, initially, tank A contains pure water and tank B contains 20Kg of salt, determine the mass of salt in each tank at time t>=0.
