How long is Dallas to Atlanta?

Excuse me, I was wondering if you could help me with a question about travel distances. Specifically, I'm curious about the duration of a trip from Dallas to Atlanta. I'm planning a journey and would like to have an idea of how long it might take to get from one city to the other. Is there a standard travel time that I should be aware of, taking into account various modes of transportation like driving, flying, or perhaps even taking a train? I'm hoping for a rough estimate to help me plan my itinerary more effectively. Thank you in advance for any assistance you can provide.
