How many hours does it take to drive 641 miles?

Well, honey, it all depends on how fast you drive. If you're cruising at a steady 60 miles per hour, you're looking at about 10.68 hours on the road. But if you're feeling like a speed demon and gunning it at 80 miles per hour, you could shave that down to 8.01 hours. Just remember to factor in pit stops for snacks and bathroom breaks – nobody wants a hangry driver on their hands.
