The Earth is spinning around its axis. At the equator, the Earth's surface moves 40,000 kilometers in 24 hours. That is a speed of about 1040 miles/hr (1670 km/hr or 0.5 km/sec). This is calculated by dividing the circumference of the Earth at the equator (about 24,900 miles or 40,070 km) by the number of hours in a day (24). As you move toward either pole, this speed decreases to almost zero (since the circumference of the spinning circle at the extreme latitudes approaches zero).

"The Universe Song" from _The Meaning of Life_ by Monty Python
Whenever life gets you down, Mrs. Brown
And things seem sad or tough
And people are useless, or obnoxious, or daft,
And you feel that you've had quite enough...
Just remember that you're standing on a planet that's evolving
revolving at nine-hundred miles an hour and orbiting at nineteen miles a second, so it's reckoned, a sun that is the source of all our power.
Now the sun and you and me, and all the stars that we can see
Are moving a million miles a day In an outer spiral arm at forty thousand miles an hour of the galaxy we call the Milky Way.
Our galaxy itself contains a hundred million stars,
it's a hundred thousand light-years side to side,
it bulges in the middle, sixty thousand light-years thick,
but out by us it's just three thousand light-years wide.
We're thiry thousand light-years from galactic central point
We go 'round every two hundred million years,
and our galaxy itself is one of millions of billions in this
Amazing and Expanding Universe!
The universe itself keeps on expanding and expanding
in all of the directions it can whiz,
as fast as it can go, the speed of light, y'know,
twelve million miles a minute, and that's the fastest speed there is,
So remember when you're feeling very small and insecure
How amazingly unlikely is your birth,
And pray that there's intelligent life somewhere up in space,
'Cause there's bugger-all down here on Earth.

Relative to what? The solar system can be compared to the center of the galaxy - I don't have the number but it is phenomenally fast. You'd have to decide what the galaxy is moving relative with to get a figure, and there's no center of the universe to compare to.
