A bird is tossing (flying to and fro) between two cars moving towards each other on a straight road. One car has speed of 27 \( \mathrm{km} \mathrm{h}^{-1} \) while the other has the speed of \( 18 \mathrm{~km} \mathrm{~h}^{-1} \). The bird starts moving from first car towards the other and is moving with the speed of \( 36 \mathrm{~km} \mathrm{~h}^{-1} \) when the two cars were separated by \( 36 \mathrm{~km} \). The total distance covered by the bird is:
a. \( 28.8 \mathrm{~km} \)
b. \( 38.8 \mathrm{~km} \)
c. \( 48.8 \mathrm{~km} \)
d. \( 58.8 \mathrm{~km} \)
