Three fast, medium and slow cars chase a cyclist in front from the same place and along the same road at the same time. The three cars spend 3 minutes, 5 minutes, and 6 minutes to catch up with the cyclist. Now we know that the fast car catches up with the cyclist every 12 kilometers per hour, CRRC travels 10 kilometers per hour, how many kilometers per hour does the slow train travel?
