Train A 40 mph
Train B 60 mph
Train A 02:10
Train B 02:25
Difference in time= 00:15 => 0.25 hours
Train A will have covered 10 miles before Train B starts from station
catch up distance= 10 miles
catch up speed = 60 -40 mph
catch up speed = 20 mph
Catchup time = catchup distance/catch up speed
catch up time= 10 / 20
catch up time= 0.5 hours
catch up time= 00:30 minutes
It will catch up at 02:55
