North Carolina (21-9, 11-6) began the day one game behind fourth-place Louisville in the Atlantic Coast Conference.
Georgia Tech (12-18, 3-15) ended its regular season with four straight losses. The Yellow Jackets lost their top scorer, Marcus Georges-Hunt, to an apparent right foot injury early in the game. He returned from halftime wearing a walking boot.
Joel Berry had a career-high 15 points and Justin Jackson added 13 for North Carolina.
It was North Carolina's second runaway win over Georgia Tech this season, following an 89-60 victory on Feb. 21. The Yellow Jackets were close in all but three of their ACC losses, including the two to the Tar Heels.
Georges-Hunt's injury was a big blow to an already limited offense. The inside scoring of Charles Mitchell, who had 16 points, and Demarco Cox, who had 14, wasn't enough to keep the Yellow Jackets close.
Georges-Hunt, who averages 14 points as Georgia Tech's only scorer in double figures for the season, limped off the court about 3 minutes into the game. He watched from the end of the bench the remainder of the half.
The cold-shooting Yellow Jackets missed their first 11 3-point attempts. Tadric Jackson finally ended the 3-point drought with less than 8 minutes remaining in the game. Georgia Tech finished 1 for 16 on 3s.
The Tar Heels stretched the lead to double figures on consecutive 3-pointers by Berry midway through the first half. Berry's third 3 of the half pushed the lead to 39-19.
