Hey friend...!!!
This concept include relative motion. When A starts moving towards B, B has already started moving towards C and as B starts moving towards C, C has already started moving towards A, and as C starts moving towards A , A has already started moving towards B
So as this cycle goes on all the three take a curved path to meet at the centre of the equilateral triangle. The centre of the equilateral triangle can be called centroid or circumcentre as both are the same points (only in case of equilateral triangle)
Please see the calculation part in the attachment.... :)
Therefore the time after which they meet is
2d/3v.
