Excuse me . Do you think I can get there in time to catch the 11:30 train ?   Well , let me see . Now it's 11:00 sharp . It's a long way to go.If I take the shortest route , we may come across a traffic jam.If I take a less heavy route , it will save us 10 or more minutes , but you'll have to pay more . Which do you prefer ?   Are you sure that I can get there in time if we take the less heavy route ?   Generally speaking , we can if we go at this speed and nothing unexpected happens .   How much more do I have to pay ?
