为了考查同学们分析问题的能力，以及将实际问题转化为数学问题的能力，中考试卷中的应用题是必不可少的．现将列一元一次方程解应用题的几种常见类型分析如下：一、行程问题行程问题的类型很多，有变速问题、相遇问题、遍及问题等．解这类问题必须利用基本关系式：速度X时间一 In order to examine the ability of the students to analyze problems and the ability to turn practical problems into mathematical problems, the application questions in the Chinese exam paper are indispensable. Now we will analyze several common types of equations for single-ary equations as follows: 1. Trip problems There are many types of trip problems, such as variable speed problems, encounter problems, and problems. To solve this type of problem must use the basic relationship: speed X time one
