M: Hello, this is Land Transport Information at Toronto Airport. How may I help you?
W: Oh, Good morning. Um, I’m flying to Toronto Airport next week, and I need to get to a town called um, Milton. Could you tell me how I can get there?
M: Milton, did you say? Let me see. I think that’s about 150 miles southwest of here. In fact it’s 147 miles to be exact, so it’ 11 take you at least—say, three to four hours by road.
W: Wow! Is it as far as that?
M: Yes, I’m afraid so. But you have a number of options to get you there and you can always rent a car right here at the airport, of course.
W: Right. Well, I don’t really want to drive myself, so I’d like more information about public transport.
M: OK. In that case the quickest and most comfortable is a cab and of course there are always plenty available. But it’ 11 cost you. You can also take a Greyhound bus or there’ s an Airport Shuttle Service to Milton.
W: Hmmm, I think for that kind of distance a cab would be way beyond my budget. But the bus sounds OK. Can you tell me how much that would cost?
M: Sure. Let’s see, that would be $15 one way, or $27.50 return ... That’s on the Greyhound.
W: Oh, that’s quite cheap—great!
