请教一道数学题 2010-3-29
各位XDJM,以下这道题我没搞明白究竟想考什么,请指点一下,谢谢了。
The participants in a race consisted of 3 teams with 3 runners on each team. A team was awarded 6-n points if one of its runners finished in nth place, where 1≦n≦5. If all of runners finished the race and if there were no ties, was each team awarded at least one point?
(1)No team was awarded more than a total of 6 points.
(2) No pair of teammates finished in consecutive places among the top five places.
我的理解,按照题干,每个队员只要比赛就至少可以得到一分,3个队员可以得到至少3分,题目是每队是否至少得到一分,这个问题本身就没有必要。不需要看下面的(1)和(2)就可得出答案。可我想我一定理解有问题,因此请大家指教。究竟这道题是什么意思。再次感谢。 |
