OK, I’ve got an up-to-day map. Let’s check the route from here to the airport.
Where are we? Oh, here we are. So we drive to the A120 and turn left.
No, we turn right. Remember that we are coming from this direction.
Oh yes! Sorry! Then we drive to the M11 motorway.
How far is that?
It’s only seven miles. We turn left to join the motorway and drive south.
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.
That’s another 15 miles, so that’s 22 miles total so far.
Then we drive west on the M25. We must be careful to turn in the right direction!
Then we drive on the M25. it turns south. When we reach exit 15, we turn left and go west along the M4.
Then we take the first Heathrow Airport. What’s the total distance?
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?
22 miles to the M25, 33 miles on the M25, and 3 after that. That’s a total of 58 miles, isn’t it?
It shouldn’t take us very long to cover that distance. Remember that we can go quite fast on the motor way.
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.
