That's almost 400,000 km/h or 110 km/s.
The timing is hard to determine from the video, and the disc of the sun is actually smaller than the screen that blocks it in the video, but the comet would travel further too because it wouldn't be right at the surface.
Gives an order of magnitude anyway.
Used this video for times:

Also, it is not touching the surface, which I am assuming you are using in your calculation, I believe it was 100,000 kms or so from the surface. I read on one website, it was give or take 1,000,000 miles per hour when it was ejected from orbit, but there was no data to back it up.
Either way, it is damn fast.
