Normal jet airliners fly at around 550 mph.
Normal jet airliners fly at around 550 mph.
In cruise flight the normal speed is 0.85 mach. Maximum speed is 0.92 mach
2250÷3=average speed. Therefore, the plane's average speed is 750km/h.
The average speed of a 747 is about 560 mph.
The average speed of a average plane is about 500-700 km/h.
The average speed of a jet plane is about 900 kilometers per hour. However, this is usually measured in knots which refers to nautical miles and this translates to about 500 knots.
Assuming you are asking about an object that is placed on an inclined plane and the only forces acting on it are gravity and friction; as the slope of the plane increases, more of gravitational force is applied down the plane and less of the frictional force is applied to the object up the plane. Unless there is no frictional force, until the plane reaches a certain critical slope the gravitational force will not overcome the frictional force and the object will not move, and the average speed for the object will be zero regardless of the slope of the plane (below this critical slope). As the slope increases there is an increase in the net force on the object down the plane which results in a higher acceleration down the plane, and with a higher acceleration it will reach a higher speed and so the average speed of the object down the plane will be higher. So, yes, it can be said that the average speed of an object down an inclined plane is dependant on the slope of the plane. If there are other forces involved, for example a motor, then the average speed will depend on these forces as well as the slope.

the average speed for a plane is 500 to 900 miles per an hour.
About 600 mph.
470 mph
The speed of light is approximately 186,282 miles per second, whereas the average speed of a commercial jet is around 500 miles per hour. This means that the speed of light is over 670 million times faster than a plane.
