Chapter 51 The time of the crime
At the scene of the crime, a pile of fragmented watch remains were found.It is found that the long and short hands of the watch are pointing to a certain scale, and the position of the long hand is just 1 minute ahead of the position of the short hand.There are no other clues to be found.But someone thought of the time when the murderer committed the crime.What time do you think it should be?

[答案：短针的一个刻度间隔，相当于长针的12分钟。短针正对着某一个刻度时，长针可能是0分、12分、24分、36分或48分中的任一位置上。分析了这种情况，就可以得到答案：只能是2时12分。推理来自对生活中各种现象的观察和思考。]
