A man lights two candles and begins a romantic candlelight dinner with his wife. The candles are of equal length, but one candle is thicker than the other.
The thick candle is designed to last for 6 hours while the thin candle is designed to last for 3 hours.
At the end of the dinner, the thick candle is twice as long as the thin candle. How long did the dinner last?
Answer
The dinner lasted 2 hours.
In 2 hours, the thick candle was 2⁄3 of the original length and the thin candle was 1⁄3 of the original length.
