Teacher: Now, understand the problem? Solve this instance: Excuse me , I need to get to Cambridge today .  Would you like to go by train or by bus ?  I am not sure , which one is better ?  The bus is cheaper but also slower . It will take about two-and-a-half hours .  And how long does the train take ?  If you take the fast train , it will take about 50 minutes .  Where do I catch the train ?  The trains for Cambridge leave from King's Cross Station . They run approximately every half hour . Most trains to Cambridge go from Platform 9 .  How do I get to King's Cross ?  The best way is to take an underground tube train directly to King's Cross . The Underground station is just round the corner from here .  Can you show me on the map ?  It is very easy . Just turn right when you leave and then turn right again at the first crossroads . The entrance to the Underground station is about 50 meters further on .  Thank you very much .  You're welcome .
