据说在过去猎狗追兔子的问题很复杂,难倒了好多数学爱好者,但是,经过长期的探索,人们找到了很多解决此类问题的办法,其中运用推理的办法是比较好的一种方法。猎人带着一只猎狗去打猎,发现一只兔子刚跑出80步,猎狗去追兔子。已知猎狗跑2步的时间兔子可以跑3步,猎狗跑4步的距离与兔子跑7步的距离相等。那么,猎狗跑多少步可以捕获兔子? It is said that in the past, the problem of retrieving rabbits by dogs was complicated and stumped many mathematical enthusiasts. However, after long-term exploration, people found many ways to solve such problems. Among them, the method of using reasoning is a better method. Hunter with a hunting dog to hunt and found a rabbit just ran 80 steps, hunting dog to chase the rabbit. Known hound run 2 times the time the rabbit can run 3 steps, hound run 4 steps distance and rabbit run 7 steps equal. So, how many steps can a hunting dog catch a rabbit?
