|||Concept of the day||| If 2 person start at the same time from the same point in a circle and the ratio of speed is a:b, then they will meet at a+b different point on the circle if the are going in opposite direction and a-b different point if they are going in the same direction. For example 2 people start running in a circular park from the same point at speeds of 20 and 30 meters per minute respectively. If they go in same direction they will meet at exactly 1 point, which will be the starting point. If they go in opposite direction they will meet at 5 different points, which will be equidistant and one of them will be the starting point.
