Input: Consider Input: I had decided that I wanted to visit my friend Paul whom lives quite a distance away . With this and my fear of air travel in mind I decided to take a train . After researching and finding one online I was well on my way to going to see my friend Paul . I drive to the station and decide that I am going to purchase a round trip ticket as this would be cheaper than just buying both tickets separately . I purchase my ticket and then go to sit down and wait for my train . Whenever my train arrives I have to get in line as they process our tickets . After all this is done I decide to take a seat by the window . I sit and fall asleep a bit as I ride on the train for hours . After a couple hours we finally reach the destination and I get off the train , excited to see my friend . 
Question: How long was their train ride?


Output: A couple of hours
