How long would it take a rocketship to reach Venus?

It is difficult to say because we do not have the rocket to travel to such a great distance, but we can estimate using data from the Moon mission: the average distance of the Moon from Earth is 385000 km, while the average distance of Venus from Earth is 108000000 km.

A rocket similar to the Saturn V, which took three days to reach the Moon, would take three times as long, or two and a half years.

This is just a guess because, of course, a mission to Venus would likely be carried out with a faster and more advanced rocket.

The time it takes for a rocketship to reach Venus depends on various factors including the speed of the rocket, the distance between Earth and Venus at the time of launch, and the trajectory chosen. Generally, it takes around 3 to 5 months for a spacecraft to travel from Earth to Venus using conventional propulsion methods.
