people best communicate in person. it is why presidents do travel to meet and greet others about the world. even when the best form of holograms enable us to teleconference it will not and cannot be as good as the real thing. electronic technology ignores the mystical because for the most part western thinking is based on the sciences which are all based on some way of measuring. We may never be able to measure the very creator of our inspiration - our muse - God. How ironic that some in our secular society are trying so hard to rid of God, that which brings forth our creative powers. But it is our souls that connect when we meet face to face and no other medium can replace it. So back to high speed transit, on the one hand we need to learn how to build cities that are compact and allow people the ability to walk or ride a bike. It is healthier because it gives us some excercise too. But there will always be the need for high speed transit between the greater distances. Jet flight travel is highly sensitive to fuel costs. There are no alternatives to date. Hydrogen fuel is possible alternative but no one has been able to figure out how to make that a safe method of fuel for flying, Skunk Works did some work with it but to no avail. Now the vacuum tube technology has been around for some time. It is viable and makes alot of sense. It is super high speed, quiet (maybe imperceptible) and the lowest energy consumption per mile of any form of high speed transit. this country was once a leader, we are becoming followers. This is not the country I was born into...what say you out there?
We can use ultrasonic planes. They can travel with that speed.
The GPS system is a network of devices that communicate by radio. Radio signals are electromagnetic radiation, just as light is, and they travel at the same speed as light does.
Average speed = Distance travelled/time to travel the distance . Average acceleration = Change of speed/time for the change .
Because the speed might change and the direction of travel might change. Hurricanes are not perfectly predictable.
Speed is the rate of change in distance, whereas velocity is speed and direction of travel. Acceleration is the change in velocity (including direction).
Simly stated, velocity is speed in a defined direction. If you travel 5mph north, the speed is the same as if you travel 5mph east, but the velocity is different.
Vehicles increased the speed that long distances could be traveled.
Waves.
An object's speed changes whenever the rate of change between the distance the object travels and the time it takes to travel that distance changes. Do not confuse speed with velocity; speed is scalar, and velocity is vector. Velocity can change when speed remains constant.

When you (or an object) travel without changing speed, then you have constant velocity (speed). This means there is no change in speed (acceleration) when you (or an object) is traveling.
The speed of light.
