＞＞＞如图，甲、乙二人绕一个长方形操场跑步，该操场长160米，宽120米..
如图，甲、乙二人绕一个长方形操场跑步，该操场长160米，宽120米，甲从A，乙从B相向而跑，结果第一次在E处相遇，E距A处60米，相遇后，甲、乙两人继续跑，已知甲、乙的速度比为3：5，问：两人能否在E处再次相遇？
题型：解答题难度：偏难来源：
假设两人能够在E处相遇，则此时，甲、乙又都跑了整数圈，由于时间相同，路程和速度成正比，所以甲、乙所行路程（也就是圈数）与速度成正比，即甲、乙所跑圈数比为3：5，只需甲再跑3圈，乙再跑5圈，二人恰好在E处再相遇。

因为篇幅有限，只列出部分考点，详细请访问。
比的应用:根据各部分的比，确定各部分与总量之间的关系，即各部分占总量的几分之几，然后按照“求一个数（这里指分配的量）的几分之几是多少”的问题解答。一般单位要统一，注意比的前后要一致，就是等号两边都是图上距离与实际距离的比，或者是反过来，再就是注意大的比大的，等于小的比小的。
