※ 引述《dw5000 (休息一下~~)》之铭言：
: Oak trees line both sides of a street for a length of
: 3/8 of a kilometers. If there is 16 meters of space between
: the trees, and each tree is 1 meter wide, how many trees are there
: along the street
: (a)22
: (b)23
: (c)42
: (d)44
: (e)46
: ANS. e
: 怎麽算都是d啊~~算不出e >.<"" 请善心人士救救我
3/8 * 1000 = 3000 / 8 = 125* 3 = 375(m)
375 / (16+1) = 22.05xxxx (单边间距数)
22+1 = 23 (单边棵数)
23* 2 = 46
