From the same point, at the same time, two pedestrians set off in the same direction along a straight highway, each traveling at a constant but different speed. After 2 hours, the distance between them was \( s \) kilometers. After this, both pedestrians increased their speeds, reducing the time taken to cover each kilometer by 10 minutes. Another 2 hours later, the distance between them became equal to \( 3s \) kilometers. Find the distances traveled by the pedestrians during the first two hours of their journey.
