No, but you stated the reasons yourself ...

These assumptions would go out the window for a realistic problem, but are reasonable for these speeds and the mixture we call air.

These are modest walking speeds for most of us. And, yeah, when we're running for the flight home, even Jerry Rice and Bob Hayes (God rest his soul) would be choking on our dust!

Now I just buy chocolate and jewelry.

25 happy years later, it's now chocolate and jewelry

I'll put this delicately ... she was probably too smart to be impressed, but saw a future source of high income (e. g., lots of chocolate and jewelry). CompSci people weren't paid very well back then. In short, you were used.
