A tank contains 60 kg of salt and 2000 L of water. A solution of a concentration 0.015 kg of salt per liter enters a tank at the rate 5 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 2.5 hours. amount = (kg) (c) Find the concentration of salt in the solution in the tank as time approaches infinity. concentration = (kg/L)

Question
A tank contains 60 kg of salt and 2000 L of water. A solution of a concentration 0.015 kg of salt per liter
enters a tank at the rate 5 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 2.5 hours.
amount =
(kg)
(c) Find the concentration of salt in the solution in the tank as time approaches infinity.
concentration =
(kg/L)
