One option is that all the three particles will meet at centroid and value of centroid is a, of an equilateral triangle.
The velocity of particle A will be divided into two components i.e. vcos60 and vsin60.
V=v+v cos
60V=v+v/2V=3v/2
Time =tS =Distance traveled by A= that by B= that by C centroid=aV=s/tt=s/vt=a÷3v/2t= 2a/3v
