在最近的一次远征北极旅行中,探险队的一名队员打算为自己找一位新娘。这一地区的居民都睡在熊皮做的睡袋里,求婚的风俗是要让新郎偷偷摸进屋去,把他的新娘连同睡袋一起背走。这位新郎须要走一段相当长的路程。他只身前去时的速度为每小时5公里,负重返回时的速度为每小时3公里,往返一共花去整整7小时。当他打开睡袋向同船的伙伴们炫耀时,他发现自己犯了一个致命的错误:他背回来的竟是新娘的外公。
In a recent expedition to the North Pole, a member of the expedition intended to find a bride for himself. The inhabitants of this area sleep in sleeping bears made of bearskin. The custom of marriage is to let the groom slip into the house and take his bride back together with the sleeping bag. The groom needs to go a long way. When he was alone, he was at a speed of 5 kilometers per hour and at a rate of return of 3 kilometers per hour and a total of seven hours round trip. When he opened his sleeping bag and showed off to his fellow shipmates, he found himself making a fatal mistake: his back was actually the bride’s grandfather.
