问题
While working on a case Dr Watson accidentally fell down a 30ft dry wishing well. Sherlock Holmes lowered him down a rope.
"Can you climb up?" shouted Holmes.
"I’ll be out before you know it. " came Watson’s reply.
But the climb wasn’t as easy as Watson had first imagined. Each hour he managed to climb 3ft--but slipped back 2ft.
How long did it take Watson to get out?
选项
答案
28 hours
解析
他一小时爬3ft,倒退2ft,就相当于一小时爬1ft,当他爬了27小时后,爬了27ft,那么剩下的3ft正好还需要一个小时,故共需28小时。
