Testing Wolfram Alpha for answers...

I asked it for the distance from Vancouver to Toronto, and here's what I got... At first glance this answer seems to be too little, but we must remember that this isn't road miles, but is the direct straight-line distance between the two points. I gave it a rough check on an old map of Canada I have on the wall, which has a scale of roughly 100 miles to the inch, and this answer turns out to be quite accurate. It should, because this is based on 'Mathematica', a computational engine designed by the same creators which solves mathematical problems and answers to formulae.
