Let the buggies start towards each other simultaneously and collide after time #t# sec.

Initial distance between the buggies#=160-25=135cm#
Distance travelled by Buggy A in this time interval#=14.55t cm#
Distance travelled by Buggy B in the same time interval#=39.27t cm#
Total distance travelled by both #=# Initial distance.
#:.14.55t+39.27t=135#
#=>53.54t=135#
Solving for #t#
#t~~2.5s#
Distance moved by Buggy A in this time#=14.55t~~36.7cm#

Along the meter stick the collision occurs at
#25+36.7=61.7cm# mark
