Problem of the Week
Problem A
Fencepost Problem

Elyas helps his parents install fence posts in their backyard. They install a row of $7$ equally-spaced posts. The posts are all the same size. The distance between the middle of the 2^nd post and the middle of the 5^th post is four and a half meters.

What is the distance between the middle of the first post and the middle of the last post?

Hint: You might start by drawing a diagram of the fence posts and labelling it with the distance you know.
