Find what will be the length of the column

Reference no: EM13712587

Problem: Athletes are running in the form of a column of length l with the same speed v. Their trainer runs towards them with the speed u (u < v). Upon meeting the trainer, each athlete turns around and starts running with the same speed v in the opposite direction.

Part A: What will be the length of the column once all athletes turn around?

I need help to find the length of the column once all athletes turn around.
