Two buses running towards each other on the same track are moving at a speed of 40km/hr and are separated by 80km. A bird takes it flight from the bus A and flies towards bus B at a constant speed of 100km/hr. Once it reaches bus Y, it turns and starts flying back towards bus X. The bird keeps flying to and forth till both the buses collide. Find the distance traveled by the bird. | Eklavya Online

# Two buses running towards each other on the same track are moving at a speed of 40km/hr and are separated by 80km. A bird takes it flight from the bus A and flies towards bus B at a constant speed of 100km/hr. Once it reaches bus Y, it turns and starts flying back towards bus X. The bird keeps flying to and forth till both the buses collide. Find the distance traveled by the bird.

The solution to the above problem can be as follows:

The velocity of the two buses approaching towards each other = (40 + 40)km/hr
The time taken for the buses to collide = 80km/hr = 1 hour.
The total distance traveled by the bird = 100km/hr * 1 hr = 100 km.
