(完整word版)相遇问题总结,推荐文档
第一讲相遇问题教学目标：1、能熟练的根据行程问题的基本数量关系，正确解答相遇问题。
2、培养综合分析、推理能力和综合运用能力。
3、养成认真读题、审题，深入分析、细心解题的习惯。
基本知识:1、概念讲解速度：速度就是每小时所走的距离。
路程：路程就是所走的距离之和。
2、三个基本量距离、速度、时间三者的关系。
距离=速度×时间速度=距离÷时间时间=距离÷速度3、相遇问题的特点及计算方法。
特点:（1）两者从两地出发。
（2）沿相反方向运动。
公式 :(1）总路程=相遇时间×速度和(2)相遇时间=总路程÷速度和(3)速度和=总路程÷相遇时间(4)路程和=甲路程+乙路程(5)甲路程=甲的速度×甲走的时间(6)乙路程=乙的速度×乙走的时间注意:要灵活运用以上公式热身: 1、有一辆汽车每小时走80千米，走了4小时，走了多远?2、从张村到李村有24千米，小敏从张村骑自行车到李村去，每小时走8千米,要走多少小时？3从广州到长沙有720千米，有一位叔叔要赶回长沙老家办事，必须在9小时赶到，问他没小时要走多远？例1、甲、乙两艘轮船分别从两港同时出发相向而行，甲船每小时行驶20千米，乙船每小时比甲船慢7千米，经过8小时两艘轮船在途中相遇。
两港间的水路长多少千米？分析：这是一道相遇问题，由“甲船每小时行驶20千米，乙船每小时比甲船慢7千米”，可求乙船每小时行驶20-7=13（千米）。
由题意知，两船的距离每小时缩短20+13=33（千米）,这就是两人的速度和。
求两港间的水路长，也就是求8个33千米是多少千米？练习1：1、一辆客车和一辆货车分别从两地同时出发相向而行。
客车每小时行60千米，比货车每小时多行10千米，经过9小时两车在途中相遇，两地相距多少千米？2、甲、乙两人同时从A、B两地出发相向而行，甲每分钟行120米，比乙每分钟快40米，行了50分钟，两人相遇后又相距30米，求A、B两地相距多少米？例2、甲、乙二人分别从相距30千米的两地同时出发相向而行，甲每小时行6千米，乙每小时4千米。
