WebThe concentration in the first lake is m 1 Q 1, hence the flow brings in v Δ t of fresh water and carries away v Δ t m 1 Q 1 of toxic substance. Thus, Δ m 1 = v Δ t m 1 Q 1, or, in other words, d d t m 1 ( t) = m 1 ( t) v Q 1, m 1 ( 0) = m. However the question is asking "find the concentration of the toxic substance as a function of time".
