What is the geographic centre of Canada? While the answer to this
question can be disputed, you are looking for the name of a town
(not Arviat). (Gr. 5 learns about Canada, don't you know!)
If A=2, B=4, C=6, then convert the name to numbers. Add these
numbers together to create one answer. Let's call that value
variable X.
Northing = 53°33.088+X
Westing = 113°53.341-X
