I think answer is 75 miles.

The distance between first person and the last person the courier man is always 50 miles. So he covers this 50 miles delivers the packet and turns back and starts walking toward the rear. Lets say he is walking at the same constant rate as the army but in the opposite direction.
So when he is half way through the distance he would reach the rear of the army. So totally he coves 50+25 75 miles.
