这段英文是甚麼意思啊?
You are given two ropes and a lighter.This is the only equipment you can use.You are told that each of the two ropes has the following property:if you light one end of the rope,it will take exactly one hour to burn all the way to the other end.But it doesn’t have to burn at a uniform rate.In other words,half the rope may burn in the first five minutes,and then the other half would take 55 minutes.The rate at which the two ropes burn is not necessarily the same,so the second rope will also take an hour to burn from one end to the other,but may do it at some varying rate,which is not necessarily the same as the one for the first rope.Now you are asked to measure a period of 45 minutes.How will you do it?

给你两根绳子和一个打火机.这就是你所有可以使用的装备.你被告知每根绳子都有如下特性：如果你把绳子的一端点燃,那么需要整整一个小时来把整根绳子燃尽.但是燃烧的速度并不平均.也就是说,其中一半的绳子会在5分钟内燃尽,而另一半需要55分钟.两根绳子燃烧的速率也不一样,所以即使第二根绳子也会和第一根一样用一个小时燃尽,但是速率很可能和第一根不一样.现在的问题是,让你来判断绳子燃到哪里是45分钟?你会怎么做呢?
