Question

2. Two trains move from station A and station B towards each other at the speed of 50 km/hr and 60 km/hr. At
the meeting point, the driver of the second train felt that the train has covered 120 km more. What is the
distance between A and B ?
1. 1320 km
2. 1100 km
3. 1200 km
4.960 km
5. None of these​

Answer 1

Answer:

Let the two trains meet after x hours. Then, 60x−50x=120⇒10x=120⇒x=12hrs

Distance AB = (Dist. covered by slower train) + (Dist. covered by faster train)

=[(50×12)+(60×12)]km

=600km+720km=1320km
