《中小学数学》2009年第11期刊登了赵平的《教学设计应更简捷》一文.文中巧妙地用“菱形图”解决了货物调配问题,引起笔者较大兴趣.笔者对“菱形图”的用法作了进一步的思考和探索.题1(原问题):A城有化肥200吨,B城有化肥300吨,现要把这些化肥全部运到G、D两乡,从A城运往C、D两乡的费用分别为每吨20元和25元,从B城运往C、D两乡的费用分别为每吨15元和24元,现C乡需要化肥240吨,D乡需要化肥260吨,怎样调运整个运费 “Primary and secondary mathematics” in 2009 eleventh published Zhao Ping’s “teaching design should be more simple” article.The article clever use of “diamond” to solve the problem of goods deployment, causing a greater interest in the author of the author Question 1 (the original question): A city has 200 tons of chemical fertilizers, B city has 300 tons of chemical fertilizers, now these chemical fertilizers should be transported to G, D two townships, from A city to C, D two townships costs 20 yuan and 25 yuan per ton, from B City to C, D two townships costs 15 yuan and 24 yuan per ton, now C Township need fertilizer 240 tons, D Township needs 260 tons of fertilizers, how to transport the entire freight
