If you go online and try to find out how long would it take you to see al the art pieces at the Louvre Museum in Paris, you get answers like these: 25 days if you spend 60 seconds in each piece, or 100 days for 30 seconds, or 6 days for 30 seconds, or 90 days with 4 seconds in each piece...
There is definitely some confusion in this matter. So, in order to settle it, here is (our) version: there are 35,000 pieces of art in the museum, if you divide them by 10 seconds on each piece the result is 4.05 days. Now you know. However, it's unlikely that we'll spend more than 5 hours running from one room to the next!
