Actual travel time and when you'll actually get the letter/package are two different things. Mail vs. UPS/FedEx/DHL can be completely different as well.
By the description on USPS website, most "types" of postage should travel that distance in 1 to 2 days.
Nothing is 100% definite with shipping though and other factors can affect the time a package can take. When (time of day and the actual day) items are picked up can affect the travel time as well.

How long does it take mail from Miami FL to Orlando？-Well, you know, it really depends on a bunch of factors. The type of mail service you use can make a big difference. If it's regular first-class mail, it could take anywhere from 2 to 5 business days. But if you go for something like priority mail or express mail, it might get there a lot quicker, like in 1 to 2 days. Oh, and the volume of mail being processed at any given time can also affect the delivery time. So, it's kind of hard to give an exact number, but usually it's within that 2 to 5 days range for standard mail.
