The upcoming question is complemented by three statements, labeled I, II, and III. Your task is to identify which statement, or combination of statements, provides sufficient information to answer the question at hand.

Two trains, labeled as A and B, are initially at a distance of 'X' kilometers from each other (where 'X' is more than 2 kilometers and the lengths of the trains don't significantly influence the distance), what is the value of 'X' given that the speed ratio of train A to train B is 5 to 3?

I. The combined length of both Train A and Train B is 450 meters, and they meet after traveling towards each other for a duration of 1 hour and 15 minutes.

II. Train A is able to pass a platform that is 220 meters long in 24 seconds, while Train B is capable of crossing a different train, Train C (which is 230 meters long, moving in the opposite direction, and has a speed of 55 km/h) in 14.4 seconds.

III. When traveling in the same direction, the two trains will meet after a duration of 5 hours.
