Coming to town, need traffic advice

Hi, I have a work meeting Monday morning at 9 at UD Curran Place and will be driving up from Cinti, so basically right up 75. Google Maps says 46 minutes, but how much should I add for rush hour traffic? Does 75N get really congested between 8 and 9?

Second question: If I run out to Giordano's Pizza in Beavercreek at 4 when the meeting ends, taking 35 to 675, how bad is that going to be? Again Google says 17 minutes, but what about rush hour?

And for the last leg, what are 75S and/or 675S like at 4-5?

thanks for any advice!

ETA: Dayton traffic was so much better than Cincinnati, even around Beavercreek. The only bad traffic I encountered was on 75 south of Lockland coming home. And I appreciate the restaurant suggestions and will check them out if I end up back up there, but Giordano's was my kid's choice for birthday dinner. Thanks!
