Train A speed 40 mph
Train B speed 44 mph

Train A passes station at 04:20
Train B passes station at 04:50

Difference in time= 00:30 30
Train A will have covered 20 miles before Train B starts

catch up distance= 20 miles
catch up speed = 44 -40 mph
catch up speed = 4 mph

Catchup time = catch up distance/catch up speed
catch up time= 20 / 4
catch up time= 5 hours
catch up time= 300 minutes
