Then why in calculating upstream where the direction of velocity of stream is against the direction of velocity of boat in still water we subtract the former from the latter even when they are opposite to each other?

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)?
