Answer / deepika
It will taka 12 sec.
bcz they cover 50 cm in 4 sec. (100 in 2s and then reverse
50 in 2s)'
according to if we calculate then at 12s they both will be
at the center and will collide. dnt calculate reverse going
distance at colliding situation. bcz it just asked for
colliding not for static condition.
