How Fast Does the Earth Rotate?
by Fraser Cain, universetoday.com -- May 20, 2013
You might be surprised to know that a spot on the surface of the Earth is moving at 1675 km/h or 465 meters/second. That’s 1,040 miles/hour. Just think, for every second, you’re moving almost half a kilometer through space, and you don’t even feel it.
From:
Wikipedia, the free encyclopedia
So to recap, we are spinning around the Earth's axis, this fast:
1,675 km/hr
0.5 km/sec
1,040 mi/hr
1,040 mi/hr div 3600 sec/hr = 0.3 mi/sec
But wait there's more ...

How fast does the Earth move around the Sun? [...]
Earth's average distance to the Sun is 150,000,000 km (93 million miles), therefore the distance it travels as it circles the Sun in one year is that radius x 2 x pi, or 942,000,000 million kilometers in a year of 24 hours/day x 365 1/4 = 8,766 hours so you divide to get 107,000 km/h or about 67,000 mph.

So to recap, we as a passenger on Earth are moving around the sun, on average, this fast:
107,000 km/hr
107,000 km/hr div 3600 sec/hr = 30 km/sec
67,000 mi/hr
67,000 mi/hr div 3600 sec/hr = 19 mi/sec

Does The Sun Move?
by Jerry Coffey. universetoday.com -- March 22, 2010
The Sun and the entire solar system orbits around the center of the Milky Way galaxy. The average velocity of the solar system is 828,000 km/hr.
[...]
The diameter of the Milky Way is about 100,000 light years and the Sun is located about 28,000 light-years from the Galactic Center.

ganymede.nmsu.edu -- Measuring the Universe
So to recap, we as life forms in the Milky Way galaxy, are rotating around the center of our galaxy, about this fast:
828,000 km/hr
828,000 km/hr div 3600 sec/hr = 230 km/sec
since 1 km = 0.621371 miles
828,000 km/hr * 0.62137 = 514,494 mi/hr
514,494 mi/hr div 3600 sec/hr = 143 mi/sec
But wait -- you guessed it -- there's more ...
Facts About the Milky Way

[...]
The Local Group is calculated to move relative to the CMB [Cosmic Microwave Background radiation] at about 600 km/s (2,200,000 km/h), which is pretty darn fast!

So to recap, we as riders in our Milky Way galaxy, are moving relative to the "static" echo of the Big Bang, at about this mind-numbingly speed:
2,200,000 km/hr
2,200,000 km/hr div 3600 sec/hr = 611 km/sec
since 1 km = 0.621371 miles
2,200,0000 km/hr * 0.62137 = 1,367,014 mi/hr
1,367,014 mi/hr div 3600 sec/hr = 380 mi/sec
From: dailygalaxy.com -- "The Great Attractor"
So assuming all these 4 motions are "additive" -- how FAST are we moving, when we "combine" them ALL together?
The grand total of your current "universal" speeds (daily, yearly, galactic, the local slide towards the "great attractor") is roughly:
3,136,675 km/hr
872 km/sec
1,949,548 mi/hr
542 mi/sec
(... give or take a few blinks of the eye.)
Don't look now, but you're moving much, much faster than the orbiting space station:
It travels at an average speed of 27,724 kilometres per hour (17,227 mi per hour).
So why in the world, aren't we suffering from
constant sea-sickness?
Good question. Here's a good answer:

The ground feels firm and solid beneath your feet. Of course, the Earth is rotating, turning once on its axis every day. Fortunately gravity keeps you firmly attached to the planet, and because of momentum, you don’t feel the movement -- the same way you don’t feel the speed of a car going down the highway.

SOOOOO ... Happy Trails, my fellow travelers ... remember to stop once in a while, and enjoy the View.
