I live where 635 & 175 cross, WHY does Google maps say Mesq. Walmart on 80 (map says 7 miles) is closer to me than Seago. Walmart on 175 (map says 7.5 miles)? There's no way that's possible!

Yes that sounds right I guess depending on where u are

If its going by the miles from where you are it'll consider it closer. But you have to take in thought. It goes by the speed limit to get the time of arrival. And to be truthful does anyone really go 60 on the highway. Or do the speed limit unless they see a cop.

No comment I like both depend on which area I'm traveling.

You are closer to the one on 80
