Expanding Highway

Imagine this highway being stretched like a rubber band to double its length in only a second. Two lamp posts next to one another will therefore be 10 metres farther apart after a second. In the same time period of a single second, two lamp posts that were initially 50 metres apart will be an additional 50 metres apart. The speed at which they move away from one another will be five times faster than the two adjacent lamp posts.
