A solution to last week’s challenge can be found here. 
Weekly challenges are a great way to experiment with some tools in Designer that you don't normally get to use. They are also a great way to experiment with new methods of solving when you check out the ways other people solved the same challenge. Everyone has their favorite tools and it's easy to have a go-to method when presented with a given challenge.
This week, the challenge is to use some mental flexibility while solving. The dataset provided has x,y coordinates for our Irvine and Broomfield offices. Your challenge is to find 3 different ways of solving the problem: Find the x,y coordinates of the point that lies exactly in the middle of these two offices.
