Train A 80 mph
Train B 96 mph
Train A 04:20
Train B 04:35
Difference in time= 00:15 => 0.25 hours
Train A will have covered 20 m before Train B starts from station
catch up distance= 20 m
catch up speed = 96 -80 mph
catch up speed = 16 mph
Catchup time = catchup distance/catch up speed
catch up time= 20 / 16
catch up time= 1.25 hours
Train B will catch up 1t 5.50 pm
