Question 29
Alan and Ben start running, at the same instant, along the running track from $A$ and $B$ respectively. They are running away from each other until they meet at $C$. After which, Ben turns to run in the same direction as Alan. When Ben passes $B$, Alan passes $A$. Given that Alan has run 800 m in total when he meets Ben the second time and that $AB=BC$, find the total length of the running track. Assume their speeds have been constant throughout the journey. Enter the length in metres.
