initially a large tank with a capacity of 300 gallons contains 150 gallons of clean water. A solution of salt with a concentration of 2 lb / gal flows into the tank at a rate of 50 gal / min. The solution is perfectly well mixed while the solution is extracted at a rate of 25 gal / min. Find:

a) the amount of salt in the tank at the time it is filled (in pounds)

b) the speed at which salt is coming out at this time (in pounds per minute)

c) The amount of salt that has left the tank since the beginning and until that moment (in pounds)

A tank initially contains 10 liters of clean water (with no salt in it). Every minute, a solution containing one liter of water and one gram of salt is added to the tank, and two liters of fluid are drained from the tank. The fluid in the tank is mixed continuously so that the salt is distributed evenly throughout the water in the tank. How many minutes does it take for the tank to contain 2 grams of salt?
