[speaker001:] Ok, I 'Ve got an up-to-day map. Let 's check the route from here to the airport.
[speaker002:] Where are we? Oh, here we are. So we drive to the A120 and turn left.
[speaker001:] No, we turn right. Remember that we are coming from this direction.
[speaker002:] Oh yes! Sorry! Then we drive to the M11 motorway.
[speaker001:] How far is that?
[speaker002:] It 's only seven miles. We turn left to join the motorway and drive south.
[speaker001:] According to the map, we get off the M11 at the second junction and join the M25. That 's the motorway that goes around the edge of London.
[speaker002:] That 's another 15 miles, so that 's 22 miles total so far.
[speaker001:] Then we drive west on the M25. we must be careful to turn in the right direction!
[speaker002:] Then we drive on the M25. it turns south. When we reach exit 15, we turn left and go west along the M4.
[speaker001:] Then we take the first Heathrow Airport. What 's the total distance?
[speaker002:] The journey around the M25 is 33 miles and then 3 extra miles to get to the airport. So how many miles is that together?
[speaker001:] 22 miles to the M25, 33 miles on the M25, and 3 after that. That 's a total of 58 miles, isn 't it?
[speaker002:] It shouldn 't take us very long to cover that distance. Remember that we can go quite fast on the motor way.
[speaker001:] We can only go fast on the motor ways if there isn 't much traffic. I think we should allow ourselves plenty of time to get there. Being early is much better than being late.
