By "east" I'm guessing you mean the northeast, New York and places farther north.
If you're speaking of the time after railroads were built connecting the principal cities, then travel from New York City to New Orleans could be done in maybe three or four days, a week at most. Before this time the fastest way was by coastal ship, but this was only good between towns on the coast. This was where most large towns were, because water transportation was the best way before railroads. New Tork to New Orleans was two to three weeks, depending on a number of factors.
If you mean overland, weeks. It was 1944 before the date of the inauguration of new presidents was moved back, from March 4, which it had always been, to the present January 20. It had been March 4 to allow the new president time to travel to Washington DC. There were nothing but dirt roads, often nothing but mud, few bridges, no signs. There were some ferries operated by private people for profit to carry travelers across rivers, and some toll bridges, also privately owned and for profit. Otherwise, rivers and streams had to forded - waded across at known shallow places. There was one "major" road, the north-south "Post Road" about where I-95 runs up the east coast today. But it was still only a dirt road and nonexistent in places.
When John Adams was elected in 1800, Abigail took a ship from Massachusetts to Baltimore, then was going to go overland the forty more miles to Washington. This was planned as a two day journey, with an overnight layover at a friend's home. When the road would get bad, with deep mudholes, new passersby would go around and start a new path. None of these were marked, and often there would be six or seven around a bad place, but you couldn't know which was the best and might get stuck. Abigail got lost, hopelessly lost, and would have had to spend the night in her carriage if her overnight host had not grown worried and sent out parties which found her. And this was the first lady of the US, trying to travel a relatively short distance between one of the nations largest seaports and its capital.
In many counties men were required to work one day a year on the public roads or pay a fine. They had to bring their own tools. You can imagine just how good these roads were.
How long is a railway line? The journey time depended if the services were express or stopping, and on the distance and number of stops, as much as train speeds, but by the end of the 19C the fastest trains could generally manage about 60mph mean speed on the level.
3 to 4 weeks in a boat. it was cold and cramped and often people would grow sick on the trip over

By the early 1800s, the steam engine had become compact enough to support long distance travel. This was the first time goods could be transported over land by means other than a human or an animal.
It was very hard. To travel any distance took several days. A person going 30 miles by horse or wagon would have to leave home for 2 days to get there and another 2 days to go home. Not only was the trip long, but people had problems getting around after dark. There were no lights to see by so travel at night was dangerous.
Since the later 1800s.
It took anywhere from six to ten days, depending on the trains you caught. Many people stopped for a couple of days in Chicago to rest from the journey.

Trains made it easier to travel long distances
Trains meant that long distances were not an obstacle to travel.
Trains made it easier to travel long distances
boats
About 6h45 (with a change of trains at Brussels).
on rivers
Around 8 hours with 2 or 3 trains.
For long-distance travel, they mostly used trains and passenger ships.
It takes long :) Croatian rails and trains are mostly old, with a few exceptions.
Airplanes are the fastest way to travel a long distance. - Over short distances, some trains may be faster
