The speed limit drops drastically once you get into Edmonton, and congestion increases, and there are traffic lights, and so on. You can't maintain 130 km/h into the centre. You are making a pretty unrealistic calculation. And just because many people drive that fast, doesn't mean a "typical" driver does. Other comments say 3 hours and 3-4 hours which is much more in line with my experience. Of course, it depends heavily on where you start, where you finish, time of day, and so on.
