Narrative:

My flight landed and was rolling out on runway 30. A training flight was doing an approach to runway 25. During xfer of control to captain at 70 KTS, tower issued exit instructions. This was a very busy time for flight crew. Captain taxied onto active runway 25 by mistake, thinking this was correct route. Trainer aircraft was told to go around and we taxied to gate. The answer is simple -- when given instructions at unfamiliar place, you must stop and verify before you cross a runway.
