How fast does an avrage rocket travel?

This maximum speed is 670 feet per second or about 3.5 times as fast as the average speed. How does a rocket travel to low Earth orbit? The speed required for LEO (Low Earth Orbit) is abput 17,500 mph. A rocket launched vertically must reach this speed by the time the payload, typically a crew capsule or a satellite, is released. So the rocket accelerates from zero to this speed in about 8 and 1/2 minutes.
