Would I be able to drive 470 miles one way, give a presentation, and drive another 470 miles back the same day?

I'm planning to take a 7 hour trip one way for a presentation. It is about 470 miles of driving through the DC area. Would I be able to drive that much in a day, give my presentation (about two hours), and drive back later that day? Is that too much? Would I be too tired once I get there? Any advice is appreciated. show more I'm planning to take a 7 hour trip one way for a presentation. It is about 470 miles of driving through the DC area.
