纵观历届全国各地的中考试题,出现了一大批“相遇再行”型应用题,本文介绍简捷处理此类问题的公式解法,供同学们参考. 若甲、乙两人同时分别从A、B两地出发,相向而行,经过t小时相遇,相遇后两人各用原来速度继续前进,甲再走t_1小时到达A地,乙再走t_2小时到达B地,则t和t_1、t_1之间满足关系:t~2=t_1t2. Looking at the examination questions in various regions across the country, there appeared a large number of “reunite and re-apply” types of application problems. This article introduces the formulae to solve such problems in a simple and convenient way for students to refer to. If both A and B are at the same time from A, B Starting from the two places, facing each other, after encountering for t hours, after meeting each other, they continue to use their original speed to continue. A then walks for t_1 hours to reach A. B then takes t_2 hours to reach B. Between t and t_1, t_1 Satisfaction relationship: t~2=t_1t2.
