本刊2003年第2期发表的《此题真的难用代数法求解吗?》(以下简称《此》文)和2004年第2期发表的《也谈通讯员所走路程的解法》(以下简称《也》文)都讨论了这样一个问题:一列一字形队伍长120 m,匀速前进,通讯员以恒定速率由队尾跑到队首,又立即跑回队尾,这过程中队伍前进了288 m,则通讯员在此过程中所走的路程是多少?
This issue was published in the second issue of this issue of “Is It Really Difficult to Solve Using Algebraic Method?” (hereafter abbreviated as “this article”) and in the second issue of 2004 “On the Solution to the Distance of Correspondents” (below). The abbreviation “Ye” also discussed such a problem: a single-lined team was 120 m long and progressed at a constant speed. The correspondent ran from the end of the team to the head of the team at a constant rate and immediately ran back to the end of the team. During this process, the team progressed 288 m, what is the distance that the correspondent takes in this process?
