Train A speed 100 mph
Train B speed 110 mph

Train A passes station at 06:10
Train B passes station at 06:22

Difference in time= 00:12
Train A will have covered 20 miles before Train B starts

catch up distance= 20 miles
catch up speed = 110-100 mph
catch up speed = 10 mph

Catchup time = catchup distance/catch up speed
catch up time= 20/10
catch up time= 2 hours
catch up time= 8:22 am
