In my experience for long trips Google Maps doesn’t account for stops, especially if you’re stopping for sit-down meals or traveling with several people. In fairness Google would have no way to gauge that. More people = more delays usually. For a solo driver stopping only for fuel, bathroom, and a few snacks it should be accurate. But just one exit where the place you’re going turns out to be a few miles off the Interstate can easily cost you 30 minutes extra.
