In fact, in Brain Master, we often encounter the problem that a candle with a height of 50 cm can burn for 3 hours. In fact, there is no need to worry, just these few small steps can solve this problem.
Question: A candle with a height of 50 cm can burn for 3 hours, and another candle with a height of 70 cm can burn for 6 hours. How long does it take to make the two candles the same height?
Answer: 6
Analysis: You don’t need to think too much about this level, and the question doesn’t say that when you need to burn it early, let the two candles have the same height. No matter when the candle is lit, the candle will be the same height after burning.
