A: how long will it take us to drive to London? B; I think it's a distance of 180 kilometers from here to London, so it should be a two-hour drive on the motorway. A; that's unless there is a traffic jam. It could take three hours. B; you're right. We will be able to travel at high speeds at the beginning and end of the journey, because we will be in built-up area. A: so, shall we allow three hours to cover the distance? B; ok. You haven't seen my company car, have you? A; no. let me take a look….it's longer than my car. B: I think it's over five meters long. I can't remember exactly. It has a maximum speed of over 200 kilometers an hour. A; wow! That's fast! I don't think we will be traveling that fast on the motorway. B; we can't. if we went that fast, we would break the speed limit.
