等边三角形相交所需的时间-yiteyi-C++库

给定等边三角形边的长度（s），以及标记在三角形顶点上的每只动物的速度（v），找出它们相遇的时间，如果它们开始向右对方向移动，形成一条轨迹。

null

例如：

Input : s = 2, v = 5Output : 0.266667Input : s = 11, v = 556Output : 0.013189

推荐：请尝试你的方法 {IDE} 首先，在进入解决方案之前。

方法： 要计算动物相遇所需的总时间，只需取A除以两个顶点彼此接近的初始速率即可。拾取任意两个顶点，可以看到第一个点以速度v沿第二个点的方向移动，而第二个点则沿第一个点的方向移动（只需沿着三角形边之一获取组件）。参考： StackExchange
