大家知道，钟表问题历来是大家比较熟知的初中数学竞赛中的热点内容．近年来，一些介绍此类问题的文章散见于各级各类读物上，但大都局限于利用角度换算的方法，初学者较难掌握．本文独辟蹊径，采用直接设未知数列一元一次方程的方法来巧解钟表问题．让我们先来熟悉一下表盘上? As we all know, the issue of watches has always been a hot topic in the junior high school math competition that everyone is familiar with. In recent years, some articles that introduce such problems have been scattered on various types of books, but most of them are limited to the use of angle conversion methods. Beginners are harder to master. This article is unique and uses the method of directly setting the unknown one-dimensional first-order equation to solve the clock problem. Let us first familiarize ourselves with the dial?
