total distance=350 m
speed of A= 7m/s
speed of B= 3m/s
when they run in opposite direction means towards each other then their relative speed= 7+3=10 m/s
so time when they meet each other= 350/10= 35 min.
and if they are running in same direction they will not meet each other, path or track is not circular
