    Pretty sure the answer is just “40 minutes” and it is a question to make someone think about what they are doing rather than automatically solve every task.

      But it’s still wrong, though, as the 9th is about 70 minutes.

      There’s even a myth saying that the 9th was the determinant for the length of the original CD.

        IIRC the speed of the 9th symphony is somewhat controversial because what markings we have on original sheetmusic are significantly faster than it’s normally played.

        Symphony music in general is going to vary a decent bit depending on what bpm(s) the conductor is choosing.

        I’d like to think it’s a really clever question about making people verify what’s written before them, rather than taking everything at face value and absolute fact.

        Yeah, I’m glad we got the length handled. Those CDs that looked like a sub sandwich were so awkward to handle…

      This is similar to something I assumed right before I had a long argument with a high school physics teacher. We ended up agreeing that he just didn’t really care.

      I remember something similar from a kids riddle book like 30 years ago about cooking stuff in an oven

      Or 80 and it’s a question to learn extracting information

      Like saying “let pi = 3” the point isn’t that pi is equal to 3. It’s that you can take that information and solve the rest of the expression
