Answer:
As shown in figure, car-A travels towrds East with velocity VA = 36 km/hr and
Car-B travels towards north with velocity VB = 24 km/hr.

Relative velocity VBA of car-B with respect to car-A  is in west of north direction as shown in figure. 
magnitude of VBA = begin mathsize 12px style square root of 36 squared space plus space 24 squared end root space equals space 43.27 space m divided by s end style and its direction is tan-1(36/24) = 56.3º west of  north.
Relative velocity VAB  of car-A with respect to car-B  is in south of east direction as shown in figure. 
magnitude of VBA = begin mathsize 12px style square root of 36 squared space plus space 24 squared end root space equals space 43.27 space m divided by s end style and its direction is tan-1(24/36) = 33.7º south of  east.

Two trains T1 and T2 simultaneously start towards each other at speeds of 40 km/hr and 60 km/hr respectively. An eagle is sitting on the engine of train T1. The moment the trains start, the eagle starts flying towards the second train. Immediately, on reaching the second train, the eagle heads back towards the first train. Immediately on reaching the first train, the eagle reverses the direction and starts flying towards the second train. This process continues till the two trains meet. If the distance between the trains is 200 km and the speed of the eagle is 80 km/hr, what is the total distance travelled by the eagle in the forward direction (i.e., in the direction towards the second train)?
