Train A 80 kmph
Train B 90 kmph
Train A 12:25
Train B 12:37
Difference in time= 00:12---- 0.2hours
Train A will have covered 16 miles before Train B starts from station
catch up distance= 16 miles
catch up speed = 90 -80 mph
catch up speed = 10 mph
Catchup time = catchup distance/catch up speed
catch up time= 16 / 10
catch up time= 1.6 hours
catch up time= 96 minutes
It will catch up at 14:13 ==> 2:13 PM
