A bird is tossing (flying to and pro) between two cars moving towards each other on a straight road. One car has speed of `54 kmh^(-1)` while the other has the speed of `36 kmh^(-1)` . The bird starts moving from first can towards the other and is moving with the speed of `36 kmh^(-1)` where the two cars were separated by 36 km . The total distance covered by the bird before the cars meet each other is

Options

A. 14400 m
B. 1440 m
C. 244 m
D. 24400 m

Answer

A

Explanation

The total time duration for the two cars to meet
`= ("Total distance")/("Relative velocity") `
`= (36)/(54 + 36)`
`T = (36)/(90) = 0 . 4 h`
In this drration ,the distance travels
`= 36 xx 0.4 = 14.4` km
14400 m
The total distance coverad by the bird before the cars meet each other is 14400 m .
