Question 4
A tree is planted every 25 m along a street from one end. There are 15 trees. How long is the street in metres?
Editorial endpoint convention: the 15 trees include both ends of the measured street segment; its length is the span from the first tree to the last. The source does not explicitly specify the far endpoint.
