The speed of car-1 is 18 km/h and the speed of car-2 is 27 km/h. Therefore, the relative speed of the cars = 18+27=45 km/h (since they are moving in opposite direction) The cars are separated by 36 km. So the time taken by the cars to meet is (distance /relative speed) = 36/45 = 4/5 hour. The bird is flying at a speed 36km/h from the first car.
In 4/5 hours the bird will travel 4/5*36=144/5=28.8 km.
Therefore the bird will cover28.8km when the two cars will meet.
Hope it helps you..
