Assume that the last 10-mile stretch of the 100-miler isn't severely downhill....it's either flat or slightly downhill.

i haven't done either one but i'd imagine 2:30 is more difficult than one 8 minute mile even if you're really tired
the sub 2:30. I have done the former and I was very, very far from 2:30 shape.
50% (aiming low)of runners on this site could train for a 100. maybe 5% (aiming high)could train for sub 2:30.
i've run ultras but never a 100, and even my no talent ass could put down the last 20 miles at 8mm on a 50 miler.
Cavin Woodward pretty much did both in a 100 mile track race in 1975. He passed the marathon in 2:31, and ran the 100th mile in 7:07. See
http://www.ultralegends.com/the-tipton-100-miles/
Here are some quotes from the article:
"The first mile was passed in 5:19, five miles[8km] in 27:49, ten miles[16km] in 56:27, 15 miles in 1:25:22, and 20 miles [32km] in 1:54:26....Woodward reached the marathon point in 2:31:22."
BTW, he averaged sub-six minute mile pace for the first 50 miles (4:58), which was a world best, continued on to break the 100K, 150K, and 100 mile world bests, and averaged just under 7 min/mi for the entire 100 mile race (11:38).
He was and example of a number of great ultrarunners over the past several decades who were fast and fearless. Yiannis Kouros, Don Ritchie, Bruce Fordyce, Barney Klecker, Alan Kirik, Frank Bozanich, and several other road racers come to mind from the 70s and 80s. The current generation, racing mostly on trails, has plenty of runners who fit the same mold.
Wow... I cannot believe this is the first I've heard of this historic run.
I'm sure pretty much every 2:30 guy can do the former, so I'm going to say 2:30
