Question

The coastline of the United States is 12,383 miles long. Canada's coastline is 113,211 miles longer than the coastline of the United States. How long is the coastline of Canada?

Answer 1

So this is basically an addition word problem. Let's start with what we know: the United States Coastline is 12,383 miles long and Canda's Coastline is 113,211 miles LONGER. Whenever there is a synonym for "more", that tends to be addition. So add 12,383 to 113,211 in order to get 125,594.
