The length of a space is the distance between its endpoints.
The distance between A and B is 1400 m.
We have:
[tex]Space = 200m[/tex]
From the diagram, there are 7 spaces between A and B.
So, the distance between A and B is:
[tex]AB = Space \times 7[/tex]
This gives
[tex]AB = 200m \times 7[/tex]
[tex]AB = 1400m[/tex]
Hence, the distance between A and B is 1400m.
