Yeah, but we don’t stop.
It takes as much propellant to stop the vehicle as it does to accelerate it.
So we’re going to need some sort of drive that allows constant, relatively high acceleration over longs periods to bring that number down. Say 1G for weeks, or even months and years...

1G will get you anywhere in the solar system fairly fast.

To travel half the distance to the moon would take about 1.75 hours. The other half distance spent decelerating would take the same amount of time.

Using Days and AU (astronomical units) we can see 3 days will get about 2.5 AU (halfway to Jupiter). 4.5 days will get you 5 AU (halfway to Saturn). 9 days will get you 20 AU (more than halfway to the Kuiper belt)
