1. An open tank with capacity 1000 L initially contains 300 L of water with 50 g of
dissolved salt. Brine (salt dissolved in water) with a concentration of 2 g/L is pumped
into the tank at a rate of 3 L/min, and the well-stirred mixture is pumped out of the
tank at a rate of 2 L/min. Determine the amount of salt in the tank at the instant the
tank begins to overflow.
