At 1:00 PM, Train X departed from Station A on the road to Station B. At 1:30 PM, Train Y departed Station B on the same road for Station A. If Station A and Station B are p miles apart, Train X’s speed is r miles per hour, and Train Y’s speed is s miles per hour, how many hours after 1:00 PM, in terms of p, r, and s, do the two trains pass each other?

A. \(0.5 + \frac{(p - 0.5s)}{(r + s)}\)

B. \(\frac{(p - 0.5s)}{(r + s)}\)

C. \(0.5 + \frac{(p - 0.5r)}{r}\)

D. \(\frac{(p - 0.5r)}{(r + s)}\)

E. \(0.5 + \frac{(p - 0.5r)}{(r + s)}\)
