Step-by-step explanation:
well...it seems the question is written in some other language which I do not know. Still, I try to decode the question based on the context of the figures and some words which I vaguely understand.
in my view the problem is
In what time a 120 meter long (may be train) running at a velocity of 40 kmph will cross another 80 meter long train coming from opposite direction at a velocity of 32 kmph.
the solution of above problem will be as below
net resultant speed = (40+32)
= 72 kmph
= 72*5/18 mps
= 20 mps
total distance to be covered = (120+80) m
= 200 m
time taken = distance / time
= 200/20
= 10 second.
please forgive me if I took your question wrong.
