"Meteors enter the atmosphere at speeds ranging from 11 km/sec...to 72 km/sec
...
The wide range in meteoroid speeds is caused partly by the fact that the Earth itself is traveling at about 30 km/sec (67,000 mph) as it revolves around the sun. On the evening side, or trailing edge of the Earth, meteoroids must catch up to the earth’s atmosphere to cause a meteor, and tend to be slow. On the morning side, or leading edge of the earth, meteoroids can collide head-on with the atmosphere and tend to be fast."
The "relatively slow" 11 km/sec is still 39.600 km/h, or around Mach 30 (although that depends on air density and temperature), so still pretty fast I would say...
There's no authoritatively correct reference for what "slow" or "fast" should mean in extraterrestrial contexts, however, I think it makes sense to look at it like this:
Suppose you were watching a (CGI) movie or a video of a meteor hitting Earth, with the whole globe on screen.
The diameter of the Earth is almost 13,000 km. So a meteor(oid) going even 70 km/s is going to take 3 minutes to hit from one diameter away.
It should look like it's barely moving on a planetary scale.
The scale of things in astronomy is humbling to say the least. "Close" can be 1 light-year away... That's 9.4607e+12 km. "Slow" is Mach 30. We're nothing at that scale.
"Ann Elizabeth Fowler Hodges...was an American woman known for being the first documented individual not only to be struck by a meteorite, but also to live through the encounter."
Here's another factor: When something is far away from you, it appears to travel slower. For example, the sun is ~150M kilometers away. As the earth rotates through a day, from our perspective it travels ~942M kilometers, meaning it appears to be traveling at 40 million kph through the sky. However, it's just sitting there in one spot.
First likely hit I found:
