During a 10-week summer vacation, was the average (arithmetic mean) number of books that Carolyn read per week greater than the average number of books that Jacob read per week?

(1) Twice the average number of books that Carolyn read per week was greater than 5 less than twice the average number of books that Jacob read per week.

(2) During the last 5 weeks of the vacation, Carolyn read a total of 3 books more than Jacob.

条件1说的是啥呀,半天没看懂.汗的

(1) Twice the average number of books that Carolyn read per week was greater than 5 <comma> less than twice the average number of books that Jacob read per week.

加个逗句后好理解了吧~~

哦,那这个题应该是这样的了

设Carolyn每周平均读x本书,Jacob每周读y本书

那么2x大于5

2x小于２y

MM,做GWD题有疑问时，可先用搜索功能，很多题目前人已提过并有解决方法；如果真的搜索不到，再发贴上来问。

方法：如果GWD第24套Q12，则搜索的关键词：24-12

我刚才搜了一下，有挺多的，你先看看，不明再问，好么？
