We can let the height of both candles be 12 inches. So the first candle burns at a rate of 3 inches per hour and the second candle at a rate of 4 inches per hour. We can let x = the number of hours it takes the first candle to be twice the height of the second candle.
12 - 3x = 2(12 - 4x)
12 - 3x = 24 - 8x
5x = 12
x = 2.4 hours = 2 hours 24 minutes
