Yeah runabouts can go to warp, but it's Starfleet protocol (or sound advise) not to travel inside a star system at warp. So yes the runabouts could go to warp to reach Bajor, but regulation or something means they go at impulse.
That clears that up thank you so much. It makes sense because they used the runabouts a lot in travelling to Bajor

How fast is impulse compared to warp or thrusters?
Slower than warp. Faster than thrusters.

Re: Full impulse

The main reason for not going to warp in system was because they could potentially run into something and cause a massive amount of damage, right? So how much damage could a runabout going at it's max warp do to a planet on impact?

Re: Full impulse

Trek has been inconsistent to be sure, but the general accepted practice seems to be that you don't normally go to warp within a solar system. In TMP, Kirk says in a log entry that "we must now risk engaging warp drive while still within the solar system." In the DS9 episode "By Inferno's Light," Dax argues with Kira about taking the runabout to warp within a solar system. And virtually every time we see a starship enter a solar system, they immediately slow to impulse.

Now, there are exceptions of course. Heck, the Bird of Prey in TVH goes to warp within the Earth's atmosphere! But I think, in general, the "don't go to warp in a solar system unless it's really, really, really urgent" holds.

Re: Full impulse

It's ambiguously and inconsistently depicted in Star Trek. There are lots of interesting "theories" as to what impulse speeds are supposed to be relative to warp speed... but because they are personal theories, they remain as such and you must either find one that seems "right" to you, or simply realize that it's just plain folly to try explaining accurately.

Being the last Starfleet ship chasing down a Borg cube on its way to Earth for example...

Full impulse is 1/4 the speed of light.
That's not what it says in TMP. When the Enterprise is leaving drydock:

KIRK: Impulse power, Mister Sulu. Ahead, warp point five.

So they can go at least half the speed of light on impulse power.

Re: Full impulse

^ Also, later in the film, they accelerate gradually up to warp speed. Sulu counts as high as warp point nine at one point. It's not until they get past that point that we see the warp effect and the ship disappear, thus moving faster than the speed of light.

Now, that could mean one of two things. Either the ship is accelerating at impulse power up to Warp 0.9 before entering warp, or Sulu was not actually reporting on the speed of the ship but on the warp power being generated. He could have been saying, essentially, "we've reached 90% of the power necessary to go to Warp 1" and when they got to that level of power, the ship enters warp.

The intent of the writers/director seems to have been that the ship was gradually accelerating to warp. But there seem to be no other examples of a ship accelerating in this manner, I'd have to go with the second explanation.

One could also interpret it this way --- Kirk said Warp .5.

Warp Factor .5 ^ 3 = .125c
