Dear 100 Hour Board,
What is always accelerating but never changing speed? This is a test to see how smart you all are because this is no riddle, it can be proven.

A: Dear Studying-Newton's-Cookies-And-Not-His-Laws:
If you're going to attempt to challenge the omniscience of the 100 Hour Board, I suggest choosing a question that can't be answered by anyone who took physics in high school.

If I assume that you are using "speed" as a synonym for "the magnitude of the velocity vector," then objects in circular motion are constantly accelerating (because they are changing direction) even though their "speed" isn't changing.
