How long will it take me to drive to Anchorage from Minneapolis?

I recently got a job in Anchorage and will be moving there in the beginning of March. I would like to drive so I will have a car right away. I have a friend that is going to drive with me so that we can take turns driving/sleeping. My question is how long will it take to drive to Anchorage from Minneapolis without stopping to do touristy things or sight see, just drive straight there as quickly as possible in March. Please let me know what a realistic time frame would be, THANKS
