All communications travel at the speed of light (approx. 300 million metres per second or 671 million miles per hour) from a terminal on ground to a satellite in geostationary orbit (approx. 36,000 km or 22,000 miles in altitude), then to another terminal on earth and back.
Highest-posted speed limits around the world. Kilometres per hour are on the left and miles per hour on the right.* A speed limit is the limit of speed allowed by law for road vehicles, usually the maximum speed allowed. Occasionally, there is a minimum speed limit. [1] Advisory speed limits also exist, which are recommended but not mandatory ...
0.44704. Miles per hour (mph, m.p.h., MPH, or mi/h) is a British imperial and United States customary unit of speed expressing the number of miles travelled in one hour. It is used in the United Kingdom, the United States, and a number of smaller countries, most of which are UK or US territories, or have close historical ties with the UK or US.

Anywhere on Earth (AoE) is a calendar designation that indicates that a period expires when the date passes everywhere on Earth. It is a practice to help specify deadlines such as "March 16, 2004, End of Day, Anywhere on Earth (AoE)" [ 1 ] without requiring timezone calculations or Daylight saving time adjustments.

Among the fastest animals in the sea is the black marlin, with uncertain and conflicting reports of recorded speeds. [2][3]
Typical scanning speed of an audio compact disc; the speed of signals (action potentials) traveling along axons in the human cortex. 1–1.5. 3.6–5.4. 2.2–3.4. 3.3–5.0 × 10 −9. Average walking speed—below a speed of about 2 m/s, it is more efficient to walk than to run, but above that speed, it is more efficient to run.
