A bird is tossing (flying to and fro) between two cars moving towards each other on a straight road. One car has a speed of `18 km //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 ?

Text Solution

Verified by Experts

Relative speed of cars `=18+27=45km h^(-1)`
Time required to meet `t=(36)/(45)=0.8h`
So, distance covered by the bird, s=vt
`=36xx0.8=28.8km`
