Roughly it is about 45 to 55 hours of driving time, for most travelers to get from the US-Canadian Border to Fairbanks. So it really depends on how many of those hours do you wish to put in each day. From Dawson Creek to Fairbanks, used to be given as 1,523 miles, but it has been shortened since those days. So if a person is an early riser and gets on the road early, it will take them less days than someone starting to move later in the morning and stopping sooner in the afternoon. It takes basically the same amount of fuel, no matter how you set up your days drive.
I tend to plan on 10 driving days from here in south Florida to Fairbanks. With a few days in Whitehorse, and a couple of other stops the one way trip works out to be two to three weeks for us, most of the time. On our last trip north, 2011, we spent more time in central BC playing and sightseeing, so it took longer than normal for us to get to Alaska.
It is a very personal matter as to how many miles a day a traveler can make, a lot depends on the ages of the travelers, do they enjoy driving, where is the traveler wanting to spend their time, on the way or in northern Canada or Alaska. Some people are happy with 4 hours of driving a day and setting in a campsite for the other 20 hours of the day, some are not. There isn't a right or wrong way to do it, just figure out what works for you and your companions.
In 1966, I made the trip from Anchorage to south Texas in 6 days, 800 miles a day average. But I sure don't recommend that method of travel over the Alaska Hwy. I was in a car and traveling solo, plus I had a time frame to be in south Texas by, that had serious consequences if I missed that deadline.
