+280 hi its been awhile and i got stumped on how to approach this one, can someone solve this with instructions. I believe it has to be done using implicit differention and derivatives.
-thanks
As salt water boils, the only thing that evaporates is the water – the amount of salt in the mixture remains constant. As a consequence, the concentration of the salt in the mixture increases over time. Suppose the concentration of salt in a pot of boiling water is given by c= 200/v , where c is the concentration of salt (mg/L) and v is the total amount of mixture in the pot (L). Determine the rate at which the salt concentration is changing at the moment there are 5.2 liters of liquid in the pot if at that moment water is evaporating at the rate of 0.13 L/min.
