A BIRD STARTS AT THE SAME TIME FROM BARCENA STRAIGHT TOWARDS THE MOVING TRAIN. ON REACHING THE TRAIN, IT INSTANEOUSLY TURNS BACK AND RETURNS BARCENA. THE BIRD MAKES THESE JOURNEYS FROM BARCENA TO THE TRAIN AND BACK TO BARCENA CONTINUOUSLY TILL THE TRAIN REACH BARCENA. THE BIRD FINALLY RETURNS TO BARCENA AND REST.

You can put this solution on YOUR website!
speed of train = 60 mph
distance it travels to Barcena = 84 miles
time it travels = 84/60 = 14/10 hours.
..
Irrespective of where it flies the bird keeps flying only for 14/10 hours.
That is the time the train takes to reach barcena.
distance the bird travels = speed * time
speed of bird = 80mph
= 80*14/10 hours
= 8*14
=112 miles
the bird flies for 112 miles
