I found this in one of the
All About Movement Rules of the Game articles:
Speed-Enhancing Spells
Several spells, such as haste and expeditious retreat, increase the subject's speed ratings. Apply all speed increases before adjusting the subject's speed for encumbrance.
So, that makes it sound like his
hasted speed is 60 feet, but encumbrance would reduce it. Armor itself isn't encumbrance, but it is supposed to reduce movement for medium and heavy armor. So, perhaps it is supposed to be 50 feet. That feels a bit broken to me, but unless the D&D FAQ says something else, then you're right.
So, Quinn can move 25 feet with a single move, 50 feet with a double move, and can run up to 4 times his
hasted speed up the slope, which would be 100 feet.
That feels very broken, but that's magic for you.
Quinn could easily reach Tarrak by running unless he tries to avoid getting attacked by any of the rooks. If he runs in a somewhat straight line, he'd only have to worry about going around the grounded rook next to Angus. He would reach Tarrak with 80 feet worth of movement.
Man, I really hope the FAQ says something else, but I'm not counting on it.
