Atlanta Airport Help

So me and my friends are traveling and have a connecting flight to Atlanta airport. I’m in need for some reassurance LOL

I’ll make up some times as example: let’s say our first flight is scheduled to land at Atlanta Airport for 2:30 PM, arriving at Gate D but our connecting flight is supposed to take off around 3:24, at Gate A. Is this possible to make??

My friends are saying we just gotta run, but I’m nervous that even then, we’ll miss our flight..
