consider a road with 2 cars at a distance of 100km driving forward each other. The left car drives at a speed of 40 km/hr and the right car at a speed of 60 km/hr. A bird starts at the same location as the right car and flies at a speed of 80 km/hr when it reaches the left car it turns its direction again to the opposite etc.
so the question is what is the total distance traveled by the bird?

• 160 km because when the track is 100km and bird flies with 80km/hr so to complete the track bird takes 1:15 minutes and the bird is back by the time when A is at 80km

• given that distance between two cars is 100km
  the speed of the cars are 60km/hr and 40km/hr.
  that means they will collide each other after one hour.
  therefore bird will fly for only hour.
  the speed of the bird is 80km/hr.
  therefore in one hour the bird will cover 80km.
