Using a minimum-energy (least fuel-use) trajectory like the Apollo spacecraft did, it takes about 3 1/2 days.
You could go faster, of course. But that woudl take a lot more fuel. Eventually, we may be able to build spacecraft that can get there in a day or two. But first, we just need to rebuild or capability to get there at all.

Hi,
The journey took Apollo 16 approx. 5 Earth days (1)
Depends on how fast your spaceship can travel the 384,403km
to the moon (2)

As others have stated - depends on what your intentions are. Pluto Express made it to lunar orbit in about 10 hours - but it wasn't planning on stopping.
The Apollo craft took 4 days, but that's because they wanted "free return" speeds & trajectories, meaning, if their engine failed, they wanted just enough speed for the moon to curve them back around toward Earth.
If the goal is an impact probe, you don't really care how fast you're going, since it's a kamikazi ride anyway. If you want to attempt orbit with little or no fuel, it can be a 13-day or longer voyage. Otherwise, you need to have enough fuel to slow your speed to enter orbit.
And, hopefully, reserve enough to come back home.

Depends on teh pourpose of the mission. the apollo astronautes took about 3 days to get there, but the new horizons spacecraft made moon orbit dirtance in just a few hours. It's not that nwe technology is better, is just that if you go faster, you also need more fuel to "brake" before you crash into the moon.

It depends on how fast you are going. In 1959, the Soviet-built Luna 2 was the first manmade object to reach the Moon's surface. It made the journey in 33½ hours, but it was unmanned.

It takes like 3-4 days at current speeds.

Using pedals and a chain/sprocket drive mechanism with
at least ten forward gears, it would take a pretty long time to cover the 250,000 mile distance to the Moon. Actual calculation of the time depends upon how long you will sleep each night, and how long you will actually be pedaling each day while awake. I assume you will take several rest breaks along the way...

with current technology, around 3 to 5 days....

Depends on the speed limit....
