Bully Vasya loves to run on the escalator in the metro. He runs down twice as fast as he runs up. If the escalator is not working, it takes Vasya 6 minutes to run up and down. If the escalator is moving downwards, it takes Vasya 13.5 minutes to run up and down. How many seconds will it take Vasya to run up and down the escalator when it is moving upwards? (The escalator always moves at a constant speed.)
