B) 3 minutes
C) 2 minutes
D) 1 minutes

we don't need to assume here the direction.we need to find which will take less time   so there are 2 cases   1)both moving in same direction...then time would be 2 minutes   2)both moving in opp direction then time would be 0.8 minutes   as we need the shortest time it would be the second case   Answer:0.8 minutes
