A tank contains 200 liters of brine with 20 kg of salt in the solution. Brine containing 0.25 kg per liter of salt flows into the tank at the rate of 3 L/min, and the mixture, kept uniform by stirring, flows out at the rate of 2 L/min. What is the time when the concentration of salt becomes 0.117 kg/L? 48 minutes 28 minutes 8 minutes 68 minutes

A tank contains 1000L of pure water. Brine that contains 0.02kg of salt per liter enters the tank at a rate of 5L/min. Also, brine that contains 0.07kg of salt per liter enters the tank at a rate of 10L/min. The solution is kept thoroughly mixed and drains from the tank at a rate of 15L/min. Answer the following questions. 1. How much salt is in the tank after t minutes? Answer (in kilograms): S(t) = ... 2. How much salt is in the tank after 5 hours? Answer (in kilograms):
The rate at which the body cools is proportional to the difference in temperature of the body and its surroundings. If a body in air at O degC will cool from 200 degC to 100 degC in 40minutes, how many more minutes will it take the body to cool from 100 degC to 50 degC? Your answer
