It is too difficult to tell. There is no existing average for the velocity of comets, as all comets are different. Gravitional, solar and initial velocity have a lot to due with the velocity of a comet.
Even though there is a great deal of variation, the answer would have to be very, very fast. Fast, that is, compared to earth standards. If a comet were to hit earth, for example, chances are that we wouldn't see or even know that it had hit. It would just hit. Not to scare you. The chances of a comet hitting the earth are slim to none.
a comet goes 45 mph in the sky
Fast enough.
it travels three times as fast as a comet
the speed of a comet and the rotation is far too fast for a spacecraft to land
It can exceed 100 000 miles per hour.

10,000km
Because the comet is going so fast there looks like the comet has a tail.
no..
it travels three times as fast as a comet
It depends on how fast the comet is going.
a comet is much more powerful because it is incredibly fast and it's large enough to be in orbit of the sun.
