Problem: Athletes are running in the form of a column (straight line) 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 start 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 want help to determine the length of the column once all athletes turn around.
