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?

1.	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?
Answer» Solution :Given, Speed of first car `V _(1) = 18 km//h` Speed of second car `v _(2)= 27 km//h` `therefore` Relative speed of each car w.r.t. each other `= v _(1) + v_(2)` (as both are in opposite) `=18 + 27=45 km//h` Distance between the CASE = 36 km `therefore ` TIme of meeting the cars (t) `= ("Distance between the cars")/("Relative speed of cars") = (36)/(45) =4/5 h = 0.8 h` Speed of the bird (v) = 36 km/h `therefore ` Distance covered by the bird `= v xx t = 36 xx 0.8 =28.8 km`
