Variable speeds.
Max. orbital speed 30.287 km/s (109,033 km/h)
Average orbital speed 29.783 km/s (107,218 km/h)
Min. orbital speed 29.291 km/s (105,448 km/h)
Thanks to http://convert-me.com the Average = 66620 mph.

Ballpark estimate:
The earth is about 93,000,000 miles from the sun. It makes an elliptical orbit around the sun in just a shade over a year (365.24 days).
To make our estimation a little easier, let's assume that the earth's orbit is circular rather than elliptical. If we do that, then the earth travels:
pi*2*93,000,000 = 584336233 miles in
365.24 *24 = 8765.76 hours, or
584336233 / 8765.76 = 66661 miles per hour.
In reality, the speed is a bit higher than that, not only because the shape of the earth's orbit is elliptical, but also because the entire solar system is moving within the Milky Way galaxy, and the Milky Way galaxy is moving within the universe. So that's a low estimate, but it gives you an idea of how fast we are hurtling through space.

66,486.7 mph
or
1104 miles a minute
or
18.4 miles a second
or
Mach 87 (that is 87 times faster than the speed of sound)
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 66,486.7 mph.

The Earth travels at a speed of 1,040 mph or .29 miles per second. (Around the sun.)
The Earth travels thru space nearly 67,000 mph.

If I recall correctly, the Earth moves at variable speeds around the sun because of it's eccentric orbit. When it moves closer to the sun, it gains speed and as it moves away from the sun it slows down.

The earth is speeding at about 66,660 miles per hour (107,278.87 km/h) in its revolution around the sun once ever 365.2425 days.

I'm not sure, but I seem to remember something like 11 miles a second.

thats funny you ask that because I just read in a magazine this morning, it orbits our sun at 66,000 miles an hour. whew!
