The particle will meet each other at the circumcenter of triangle ....

so each particle will have to travel a distace d /root 2 ( distance of each particle
at vertex from  circumcentre.{can be calculated using geometry}  )..

now take component of velocity toward circumcentre . by using that
the angle of equilateral triangle is 60 degrees...

and apply t= s/v to get answer..
