Nice assumptions.
Even on my long family trips I never averaged the speed limit. You hit stop and go traffic, slow downs etc, so the average is below the speed limit and oftentimes it's not a small amount.
I would presume this lady doesn't just drive, but carries some sort of cargo. There is time involved with that as well, pickup/drop off waiting, getting signatures, filling out some paperwork, then there are restroom and food brakes.
Possible? Yes. Is it probable, I would say no.
