About 8.\n\n\nTo clear up any  ambiguity contributed here by some--- The average distance from the Earth to the Sun (or 1 astronomical unit) is 8.317 light minutes. Saying it's "more" or "less" sometimes is stating the obvious-- it's an AVERAGE. Saying it's "usually" different than its average, is nonsensical. \n\nhttp://en.wikipedia.org/wiki/Light_minute

Yes, the curvature will prevent the post from being seen.\n\nThe distance you can see is approx,\ndistance ~= 3550 * sqrt(height) (height and distance in meters)\n\nSo the distance to which a height = 8848 meters post will be visible for is about distance = 330km.

Shadow means no light. So id light is cut-off or changed shadow will be formed or changed at the speed of light.\n\nCoclusion:\n========================================\nspeed of shadow = speed of light = 3x10^8 m/s\n\nor 186,000 miles/s

9 miles\n\nThat's if you were standing at the edge of a calm stretch of water (and you're approximately 5 foot 8 inches tall) - then the horizon is approx. nine miles away.\n\nObviously, if you gain more height you'd see further, and you could actually see things beyond this horizon - if the things are tall enough!

The question's a little vague, but I'll give it a shot with the following assumption: I'll pick <b>miles</b> as a unit for the distance, since the asker didn't provide one.\n\nAverage rate, in this case <b>average speed</b> specifically, can be derived by dividing total distance covered by total time used:\n\n7056 mi. / 168 hr. = 42 mi/hr (sometimes written "42 mph") average speed.
