Two boys A and B are at two diametrically opposite points on a circle. At one
instant the two start running on the circle; A anticlockwise with constant speed v
and B clockwise with constant speed 2v. In 2 minutes, they pass each other for
the first time. How much later will they pass each other for the second time?

Let the half distance of the Total circle be 3x A at the speed of V covers x distance and B at the speed of 2V covers 2x distance and thus partial distance of 3x at 2minutes, again if they run opposite they have to cover 6x distance to meet each other i.e if A covers x distance B covers 2x distance and so on
Finally x + 2x + x + 2x = 6x
3x at 2 minute
6x at 4 minute
whether I am right
