The ratio of the crawling speeds of three ants A, B, and C is 8:6:5. They crawl along a circle from the same point in the same direction at the same time. When they return to the starting point at the same time for the first time, they stop crawling. Ask how many times Ant A has caught up with Ant B (including the end time)?
