Instead of 19x = 900, where x is the even spaces between each posts.

I will use 18x = 900. Why?

Well, to explain it clearly. Take a look at your hand (either left or right). If your fingers are the posts and the spaces in between are the x or the even spaces. It would make a 5 posts and 4 spaces in between. I hope my explanation is clear.

So, in this case. There would be 19 posts and 18 even spaces.

18x = 900

x = 50 m

it would look like this:

| 50m | 50m | 50m | 50m | 50m | 50m | 50m | 50m | 50m | 50m | 50m | 50m | 50m | 50m | 50m | 50m | 50m | 50m |

| <- this sign is the post. I just draw it to emphasize more.

Now count the spaces and the posts. :) There would be 19 posts and 18 spaces. I hope you get my point. :)
