枫下沙龙 / 谈天说地 / 也出一题, 给你二根导火索, 每根可各燃1小时, 但燃烧速度不一定均匀, based on this, 请测出45分钟来.

先把第一根两头点燃,半小时燃完。记下终燃点,从对应位置及任一端点燃第二根,燃尽时就是四十五分钟。

一根同时点两头,另外一根点一头,等点两头的烧完了,同时点燃另一根的另一头,燃尽的时间就是45分钟了。

你的方法是对的,我的只适用于两根一模一样的,而且速度相同的两头摆在一起。惭愧。

no 惭愧 at all, buring both ends is the key point, which u found also.

本来我还迷糊呢,要不是您的方法提醒,我还真没那么快想出这个答案。

太旧了,一根两头点着,另一根一头点着;等前一根烧完了,把后一根的另一头也点着就行了。
