This is an example of a mixing problem. This is a question from my differential equations class. Theyâre word problems that require us to create a separable differential equation based on the concentration of a substance in a tank. To construct a tractable mathematical model for mixing problems we assume in our examples (and most exercises) that the mixture is stirred instantly so that the salt is always uniformly distributed throughout the mixture. Hence 300lb of salt, approximately. Jennell Tompkins. A typical mixing problem deals with the amount of salt in a mixing tank.
