Two trains start from A & B and travel towards each other at
speed of 70kmph and 80kmph resp. At the time of the meeting the
second train has traveled 200km more than the first.the distance
between them.
Choose the most appropriate option.
A) 2500 km B) 3000 km C) 3500 km D) 4000 km E) 4500 km
Let the distance traveled by the first train be x km   then distance covered by the second train is x + 200km   x/70 = x+200 / 80   x= 1400   so the distance between A &amp; 3000 km is x + x + 200 = 3000 km   Answer is 3000 km.
