Charolette to Atlantic

Assuming you're driving from Charlotte to Atlanta, you can use this page on Trippy. At the upper right of the page, there's some stats. Without making any stops, you're driving about 244 miles which would take between 3-1/2 to 4 hours straight.

On the other hand, if you decide to make it a casual road trip with stops, the itinerary suggests you start at 10am, stop for lunch in Greenville and check out various other places along the way, then arrive at your destination around 7:30pm after a full day of exploring.
