How many pennies per day are needed to accumulate in order to reach 11,000
there is no answer no pencils can be made in a sec Machine made pencils can be produced at more than one per second. Look up a pencil manufacturer. Across the world probably hundreds of pencils a second are being produced.
The number of cents made each year varies widely depending on demand, so even an average figure for coins per second won't be very representative. For example in 1994 almost 13 billion cents were made which works out to about 412 coins per second over an entire year. In 2009 only about 1/6 as many cents (2.3 billion) were struck so that's 70 coins per second. Of course production doesn't necessarily go on 24/7 so the actual production speed varies a lot, too. An individual coin press can make 600 to 800 coins per minute so that's 10 to 13 coins per second per machine.
100,000 pennies at one per second = 100,000 seconds 60 minutes in an hour and each minute is 60 seconds = 3600 seconds per hour 24 hours per day * 3600 seconds = 86,400 seconds per day 100,000 seconds/86,400 seconds per day = 1.2 days ----------------------( not that much )
