The speed of a commercial jetliner is around 560 miles per hour.
In a small aircraft, about 3 hours. In a commercial jetliner, about an 2 hours and 30 minutes.
The altitude of the jetliner is 6 miles.
As a passenger on a commercial jetliner, not particularly. Mainly you sit there, maybe take in a movie, eat some fiddly food and wait for the journey to be over.
That depends. In an ultralight glider probably about a week. For a seagull about a month. For a commercial jetliner about 2 hours. Define your question and the answer will be definative.

The takeoff speed of a commercial jetliner typically ranges from 130 to 180 knots (about 150 to 207 miles per hour), depending on various factors such as the aircraft's weight, configuration, and environmental conditions. Larger aircraft may require higher speeds, while smaller jets can take off at lower speeds. Each aircraft type has specific performance charts that detail the exact takeoff speeds needed for safe operation.
