I say the new movies are just basing their warp speeds on different examples to, say, Voyager and are ignoring the time/speed charts in the technical books (as all the above did)


(...of course, that leaves Voyager in a bind, their warp 9.975 being significantly slower than TOS' warp 8.4 - yet they crossed over with TOS, TNG and DS9.... it's confusing.)
TOS Warp Scale (Cochrane Scale):

V/c = WF^3

Where V = Velocity of the vessel, c = the velocity of light, and WF = the warp factor.

TNG Warp Scale:

Up to warp 9:
V/c = WF^(10/3)

Past Warp 9:
V/c = WF^[<(10/3)+a*(-Ln(10-WF))^n>+f1*((WF-9)^5)+f2*((WF-9)^11)]

Where a is the subspace field density, n is the electromagnetic flux, and f1 and f2 are the Cochrane refraction and reflection indexes respectively. Under ideal conditions values of a = 0.00264320, n = 2.87926700, f1 = 0.06274120 and f2 = 0.32574600 can be expected within a "normal" area of deep interstellar space

There is a theory about "non-normal" areas of space called warp highways. A warp highway is a region of space where interstellar conditions such as gas density, electric and magnetic fields, and local fluctuations in the subspace domain combine to allow starships to travel at speeds significantly higher than normal. These regions can consist of broad areas encompassing a number of whole star systems, or narrow corridors which can extend for many thousands of light years. You could also think of these as the same way we would use ocean currents to speed up sea travel.

The converse of the theory explains regions called "sandbars" where warp travel is impossible. One such example is the Briar Patch in Insurrection.

Warp 9.975 was (iirc) Voyager's maximum speed, given the long journey ahead Janeway and her senior staff could have made the decision only to use that speed when they had to and to travel back to Earth at a more reasonable rate of speed to preserve the engines.

Also, we often saw Voyager (especial at the start of episodes) not at warp, but obviously at sublight speeds. My interpretation is that they were "dashing and pausing," frequently slowing to sublight to perform preventative maintenance, again to preserve the engines for the long journey.

These two things are why it was going to "take them so long."

"Even at maximum speeds, it would take seventy five years to reach the Federation."

That's Janeway's exact quote. No wiggle room, it's how long it'd take if they maintained their warp 9.975, established earlier in the episode as their "sustainabe cruise velocity" (which leads one to think they can actually go faster for short periods)

As for Sans' talk of subspace field density and warp superhighways, it sounds kinda nice, but I can't buy it making a big difference on the sheer scale we see throughout Trek - the old Enterprise warps to the galactic rim and core, to and from Earth on a whim, but Voyager takes an entire lifetime? Particularly with Voyager's advanced Borg sensors post-"Scorpion"
