The length of a single-lined team is 120m, and it moves forward at a constant speed. The correspondent is at the end of the team at a constant rate. At the head of the team, they immediately ran back to the end of the team. During the process, the team progressed 2 88m. What was the distance the correspondent took in this process? The original thought that this problem can be solved by algebraic method, and that the
