一道英语奥术题a frog falls into a well.the well is 28m depth,the frog climbs 4m and gets down 2m,How many days can the frog get out of the well
14 days.
中文翻译:一个青蛙掉进了井里。井深28米,青蛙每爬4米会掉落2米。请问青蛙要多少天才能爬出井?
话说这题没给每天青蛙跳多少次,所以没法算。。
thirteen days.
For the last day it jumped out of the well, can never fall down.
也许答案是没法算?就如那位老兄说的,没说青蛙每天爬多少次。
翻译:一只青蛙落入井里,井28米深,青蛙每天爬4米,滑下2米,青蛙多少天可以出井?
解析:每天实际爬2米,12天爬24米,第13天爬4米,直接出井,所以答案13天
答案:Thirteen days
要用英语回答吗?The frog needs fourteen days to get out of the well.
