There is a row of saplings. The distance between two adjacent trees was originally 2 meters, but now it is changed to 3 meters. If one tree at the starting point does not move, then how far away is another sapling that does not need to be moved?
有一排树苗，每相邻两棵间的距离原来都是2米，现在改成3米，如果起点的一棵不动，那么最近再隔多远又有一棵树苗不需要移动？
