**Bird and the Train :** The distance between Station Atena and station Barcena is 84 miles. A train starts from Atena towards Barcena. A bird start at the same time from Barcena straight towards the moving train. On reaching the train, it instantaneously turns back and returns to Barcena. The bird makes these journeys from Barcena to the train and back to Barcena continuously till the train reaches Barcena. The bird finally returns to Barcena and rests. Calculate the total distance in miles the bird travels. The bird flies at 80 miles/hour and the speed of the train is 60 miles per hour.

**Solution:**

The train (at a speed of 60 miles per hour) travels 60 miles in 60 minutes.

Therefore,the train travels from Atena to Barcena (84 miles) in 84 minutes.

Importantly, the bird makes the journeys continuously back and forth for this same amount of time (84 minutes).

Thus, the total distance travelled by the bird = 80 miles per hour * 84 minutes

80 * 84 / 60 miles = 112 miles.
