The driving distance is approximately 322 road miles. The driving time will be about 5 hours and 36 minutes, depending on your speed and traffic conditions.
Withe average traffic conditions you can get from Cardiff in about 1hr 40m. I live in Pembroke and can do Cardiff Bay to home in 1:45 or thereabouts. Hope this helps
The driving distance between Seattle, WA and Minneapolis, MN is approximately 1655 miles. The driving time would be approximately 25 hours if you were to travel non-stop in good driving conditions....
