U 'll get da path followed resembling an exhaust fan centred at da centre of square O.
Since each has same velocity all reach O at same time.
Distance moved by each is same as a quarter of circle i.e. pi r/2
where r=dis fron a vertex to O=d/root 2
Time=[pi *d/2root2 ] / v
Rate da ans if I'm correct..Please nudge if wrong
