A tank contains 100 kg of salt and 1000 L of water. A solution of a concentration 0.05 kg of salt per liter enters a tank at the rate 10 L/min. The solution is mixed and drains from the tank at the same rate.
(a) What is the concentration of our solution in the tank initially?
concentration = (kg/L)
(b) Find the amount of salt in the tank after 1 hours.
amount = (kg)
(c) Find the concentration of salt in the solution in the tank as time approaches infinity.
concentration = (kg/L)
