1. The problem statement, all variables and given/known data Two candles A and B are 8cm and 14cm long, respectively, and are lit at hte same time. If candle B burns twice as fast as candle A, how long are they when their lengths are the same. How long is candle A when candle B burns out? 2. Relevant equations Not sure. 3. The attempt at a solution I drew a table of length's for equal time width's. So when A is 7cm ling B will be 12cm long etc. I found that they would be 2cm a piece when they are the same length and that candle A would be 1cm long when candle B burns out. Is this correct? More importantly how do I answer this question algebraically? The above seems to me like the dumb approach, but I just can't see how to model teh problem. Any help would be much appreciated!
