Airships, depending on the type,
average airships can reach a maximum speed of 125–135 km/h.
Military airships can reach a maximum speed of 120–140 km/h.
Smaller, steam-powered or early gasoline-powered airships move between 40–80 km/h.
The safety limit of all airship types: 150 km/h is the maximum, above which the pressure and air flow would be dangerous for those on board and for the airships as well. (headwinds can blow people off the airship and damage the structure).

Average speed of steam locomotives:
They move between 60–90 km/h.
---
Speed of seagoing steamships:
They move between 30–50 km/h.
Sailing ships:
The average speed of older merchant and warships in moderate winds is about 4.5 knots (about 8.3 km/h), but heavier merchant ships often only travel at 4 knots, depending on the conditions (wind, cargo weight, ship condition).
The average speed of slightly newer ships can reach 6 knots (about 11 km/h). This allows them to travel about 144 nautical miles per day.
The average speed of the latest modern sailing ships is regularly 7–8 knots (about 12–13 km/h) on long voyages. In exceptional circumstances, their average can reach 14–17 knots.
Warships can reach an average of 12–14 knots.
But with improvements and favorable winds, they can reach 20–22 knots.
A modern hybrid clipper (sail + steam, steam wheel) can already reach a fixed 12–15 knots even in calm weather. This can be increased to a small extent with improvements (copper cladding, stronger boiler, sails, etc.) with these they can reach a maximum speed of 40 knots.

land vehicles, carriages:
traveling carriages and commercial horse-drawn carriages:
Average speed: A typical stagecoach or traveling carriage can travel at a sustained speed of 8–12 km/h.
But on well-developed postal routes, with frequent horse changes, the speed can reach 15–16 km/h

Steam-powered cars:
an average (primitive) Steam-powered car has a top speed of about 16 km/h.
Slightly more modern steam-powered cars can travel at 20–30 km/h.
The very rare and special Electric-powered car can reach speeds of 50–100 km/h.
But such a car is extremely rare and very expensive. It also requires special maintenance. and because of the electric drive, the electric cells that act as fuel are difficult to obtain and expensive.
