近几年,中考命题加大了从函数图象中获取、分析、处理信息能力的考查力度,因此行程问题一改过去以方程型居多的局面,多以函数图象的形式出现,因此新型的行程题应运而生,现从2012年各地中考试题中采撷几例供同学们赏析.一、相遇问题例1(十堰卷)一列快车从甲地开往乙地,一列慢车从乙地开往甲地,两车同时出发,两车离乙地的路程S(千米)与行驶时间t(小时)的函数关系如图所示,则下列结论中错误的是().
In recent years, the senior high school entrance examination thesis has increased the ability to obtain, analyze and process information from function images. Therefore, the problem of stroke changed in the past when most of the equations were in the form of functional images. Therefore, Trip problem came into being, from 2012 around the middle of the test questions in the collection of several cases for students to appreciate.One encounter Case 1 (Shiyan Volume) A train from A to B, a local train from B to A Ground, the two cars start at the same time, the distance between the two vehicles and the distance S (km) and driving time t (hours) as shown in the function diagram, the following conclusion is wrong ().
