Answer: 48 minutes

========================================================

Step-by-step explanation:

distance = rate*time

Train A travels a distance of 100x kilometers after x hours elapse

Train B travels 150x kilometers

The two trains pass each other when their distances add up to the 200 kilometers mentioned. Assume the two trains are on separate parallel tracks.

trainA+trainB = 200

100x+150x = 200

250x = 200

x = 200/250

x = 4/5

They will pass each other at the 4/5 hour marker

This converts to (4/5)*60 = 0.8*60 = 48 minutes
