"A snail crawling on Mars would appear to be moving across the surface more than 100 times faster than the motion measured in which galaxy? (nope not the old folks driving in Florida).

Clarification: Are you talking about angular speed (e.g., degrees per second) as seen from earth?

If read you correctly, you are referring to the Andromeda Galaxy (M-31).

Yes to your question Professor. SR not the right one,but somehow you are close.

Sorry, got my galaxies mixed up; the actual answer should have been the spiral Galaxy M-33, which is a satellite of the larger galaxy Andromeda M-31.

After all, I was only a few million light years off!!)

You were only two "M"s away.

Good answer Sailracer.
