A tank initially contains 120 L of pure water. A mixture containing a concentration of p g/L of salt enters the tank at a rate of 2 L/min, and the well-stirred mixture leaves the tank at the same rate. Find an expression in terms of p, for the amount of salt in the tank at any time t. Find the limiting amount of salt in the tank as t → o.
