How long will it take to sing A million green bottles standing on the wall a million green bottles standing on the wall and if one green bottle should accidentally fall there'd be all the way to zero?

Answer 1

Well, it takes about 10 seconds per "number" using the standard tune. So that would take 10,000,000 seconds. That's 166,666 minutes which is 2,777 hours which is over 115 days. So assuming you don't stop, it would take 16.6 weeks to sing it.
