Two tanks each holding 50 L of liquid are interconnected by pipes with liquid flowing from tank A into tank B at a rate of 4 L min and from tank B into tank A at 1 L min as shown in the figure The liquid inside each tank is kept well stirre Pure water flows into tank A at a rate of 3 L min and the solution flows out of tank B at 3 L min If initially tank A contains 3 3 kg of salt and tank B contains no salt only water determine the mass of salt in each tank at time t 0 Graph on the same axes the two quantities x t and x t where x t is the mass of salt in tank A and x t is the mass in tank B Click the icon to view the figure of the tanks What are the equations for the mass of salt in each tank at time t 0 X t X t
