苏步青爷爷是我国著名数学家,他年轻时做过这样一道有趣的思考题:甲和乙从东西两地同时出发,相对而行,两地相距100公里。甲每小时走6公里,乙每小时走4公里,如果甲带着一只狗和乙同时出发,狗以每小时10公里的速度向乙奔去,遇到乙后即回头向甲奔去;遇到甲后又回头向乙奔去,直到甲、乙两人相遇时狗才停住,问这只狗共奔跑了多少公里路?在这道题里,狗在甲、乙两人之间跑来跑去,真让人眼花缭 Su Buqing Grandpa is a famous mathematician in our country. When he was young, he made such an interesting question: A and B start at the same time from east and west at the same time, and they are 100 kilometers apart. A walk 6 kilometers per hour, B walk 4 kilometers per hour, if A with a dog and B starting at the same time, the dog at a speed of 10 kilometers per hour to run to B, B met back to a ran back; After meeting A, I turned back to B until the two dogs met when they met, and asked how many miles they ran. In this question, the dog is between A and B. Come and go, really dazzling
