A letter mailed with standard postage through the United States Postal Service takes five to seven days to reach its destination. Regular mail can take even less time than that for pieces mailed from Florida to New York, but it is unlikely to ever arrive overnight, unless an expedited delivery option is used.
As of 2012, Iowa is within the 2-day USPS service area from Florida. However, if mailed late in the day, or delayed by weather, it could take longer. Under the very best conditions (mailed early, near a major city) it could actually arrive the next day.
They are mailed from Virginia.
It varies, but 2-4 business days is the norm.
