Task: Question Answering
Input (English): I walked to the bus stop near my home so that I could get to work . I brought along my purse which had my bus card in it so that I could ride without paying cash . It only took a few minutes for the noisy bus to arrive . It stopped at the bus stop and the door opened . The bus driver scanned my bus card and I walked to an empty bench near the middle of the bus . Many other passengers boarded the bus after me and soon the bus was nearly full . Looking around me , I saw a number of senior citizens as well as other young adults . There was even a woman with a sleeping baby sitting on the bus near my bench . I decided to listen to music on my smart phone while I waited for the bus to reach my destination . The bus stopped every few minutes to let other passengers on and off of the bus . After about an hour , the bus stopped at my bus stop and I got up and walked out of the bus , wishing the driver a good day . 
Question: How long was the ride?
Output (English): 1 hour
