kreynolds: I'm with you. Now I know how Crothian feels. Sheesh.
Souljourner: Because the PHB does not define how much time it takes to complete a MEA, (3 seconds, 2 seconds, or what) or if it's before during or after a Standard Action, let's redefine Speed in DnD terms:
The Real World: Speed = Distance / Unit of Time
The DnD World: Speed = Distance / Action
This is redundant, as the units of time in DnD are broken down into Turns, Rounds, and various Actions (SA, MEA, PA, FRA, ...)
So:
Normal Movement Rate = 30 ft per Action = Hustle
Half Movement Rate = 15 ft per Action = Walk
Double Movement Rate = 60 ft per Action = Run
The walking speed corresponds with kreynolds' argument concerning overland movement rates.
The running speed corresponds to x4 movement over a whole round.
The hustling speed corresponds to the PHB quotation of "hustling half the time and doing something else the other half" in that the character still has one action to spend doing something. It also corresponds to a double move being a hustle, but you hustle for twice as long: you hustle for two actions.
So, Moving Silently without penalty requires you not exceed half of the character's normal speed. By moving at a speed of 15 ft per Action, you do not exceed one half of the normal speed. No problem so far. You take your second action and again move at a speed of 15 ft per Action. You have not exceeded your speed and have moved 30 ft in a round.
MEA + MEA = 1 round
Your quote of the SRD has no argument with this:

One Tactical round can be made up of 2 MEAs. So if you walk for each of those MEAs in your round, you will be moving at 15 ft per Action. If you hustle for each of those MEAs you will be moving your base speed
per action, 30 ft. Notice that there is no other possible way to move 60 ft in a full round if your base speed is 30 if you don't take two MEAs back to back. So the hustle speed is listed meaning two MEAs. This implies that the listed walk speed is also two MEAs.
Put it this way:
A rogue begins his round moving silently 15 ft for his MEA into position behind an orc. Is that rogue able to attack the orc in the same round? Yes, and he had been walking.
Later in combat, would that rogue be able to use two MEAs in the same round to hustle to his dying friend, moving 60 ft? Yes, and he would be hustling.
Later that night, can the rogue move past his sleeping comrades without disturbing their sleep? Yes.
Can he walk twice in a round (just like he hustled twice in a round) as he doesn't disturb his comrades?
