Depends on your average speed. If you can average 60 mph it would take 20 hours. But considering that this trip would almost certainly require you to spend to night and rest then it would take 28 hours.
It obviously depends on how fast you are driving. You should be able to drive 1200 miles in about 22-24 hours.
To drive 80 miles at 80mph takes 1 hour. To drive 1200 at 80mph takes 1200/80 = 15 hours.
16 hours.
24 hours.
16 hours.
16 hours, if you do it non-stop
Distance = Speed x Time Time = Distance / Speed = 1200 miles / 65 Miles per Hour 18.4615385 Hours
It takes approx 21 hours 49 minutes and 5 seconds.
18 hours 27 minutes.

65 miles per hour .. In math, per is a key word that lets you know there is division. 65 miles / 1 hour = Speed 1200 miles / ? hour = 65/1 which is the same as ? hour/1200 miles = 1/65 ? hour = 1200/65 18.46 = how long it takes to drive 1200 miles at 65 mph.
Couple of minutes under 18½ hours. Better add some sleeping and eating time!
