Speed = distance ÷ time
→ time = distance ÷ speed = 1920 miles ÷ 640 miles/hour = 1920 ÷ 640 hours = 3 hours.
You can use the formula:distance = time x speed
The "as the crow flies" distance is about 4,928 miles / 7,930.5 km.
For knowing how an airplane flies at constant speed, follow this link: http://science.howstuffworks.com/transport/flight/modern/airplanes.htm I can't explain this in detail in writing but you can understand very well from this site
the airplane with the most fuel
Airplane fly mothers and fathers
356 kilometres is a distance, not a speed. Therefore, the two units are incompatible.
the airplane will fly farther. This is due to the fact that both the airplane and the hot air balloon use fuel. Also because the hot air balloon only means of movement is wind, While an airplane use jet propulsion. This allows the airplane to travel in any direction
pilot
As an airplane flies, a strong "wind" blows across the wing (an object moving through still air works the same way as a strong wind blowing across a still object). An airplane wing is bent so that there's more curvature on top than on the bottom. For air to get to the back of the wing, it has a longer distance to travel than if it flows along the bottom of the wing. Since there is less distance below, air doesn't travel as quickly to get to the back of the wing as it does in a path across the top, so air moves more slowly underneath.
Pilot
Any airplane that the president flies on is called Air Force One. Most often it is a Boeing 747.
The airplane is flown by a pilot who has been trained and then authorized by the appropriate authorities.
