| Aug 28, 2013 at 14:32 | comment | added | Georg | Another question: ""Write a differential equation for the amount of water in the pond at any given time."" Isn't the concentration of chemical in the pond or the amount of chemical in the pond the thing which is asked for? BTW that g is for grams of course. I wonder why they did not ask for bushels/cu furlong | |
| Aug 28, 2013 at 14:26 | comment | added | JimmyJackson | Yeah, I had initially rewrote the problem in my own words, and I replaced 'chemical' with 'pollutant', but once I started writing the question here I decided it would be best to write the problem as it was written in the book. | |

pet peeves on spelling.
