A bird is tossing between two cars moving towards each other on a straight road. One car has a speed of 18 m/h while the other has the speed of 27 km/h. The
bird starts moving from first car towards the other and is moving with the speed of 36 km/h and when the two cars were separated by 36 km. What is the total
distance covered by the bird? What is the total displacement of the bird?
The relative speed of the cars = 27 + 18 = 45 km/h
When the two cars meet together, time t is given as
t = distance between cars/relative speed of cars
= 36/(27+18)
t = 4/5 h
Therefore, distance covered by the bird in 4/5 hours = (36)(4/5) = 28.8 km
