A tank initially contains 100 liters of pure water. A brine solution con- taining 2 kilograms of salt per liter enters the tank at the rate of 5 liters per minute. Concurrently, the mixture is well-stirred inside the tank and exits through an outlet valve at the rate of 5 liters per minute. Let y(t) be the amount of salt inside the tank at any time t≥ 0. The salt concentration inside the tank reaches kilogram per liter after how many minutes?
