- Kien Hwa
This applet allows you to see how two quantities co-vary according to an invariant relationship.
Two identical candles, A and B, lighted at different times were burning at the same constant rate. When candle A had burned 20 mm, candle B had burned 12 mm. When candle A had burned y mm, candle B had burned x mm. How is y related to x?
