We want to take a train to NewYork.

Regular or express train? How much time will be saved if we took the express?

About one hour. The next express train arrives in NewYork at 3:15.

And how much more do we have to pay for the express?

First class is 24 dollars more and second class 15 dollars more.

As long as we arrived one hour earler I don’t mind paying a little extra. Then give me two second class tickets on the express,please.
