If you're asking which is faster , the Earth or a rocket the answer is we can make rockets travel faster than the Earth's motion. Think about this, we have geosynchronis sattelites that stay above a certain place on Earth, which means they match the speed of the Earth's orbit and rotation and they were put in place by rockets, so we can obviously make rockets that go as fast. The early Mecrury missions orbited the Earth faster than it rotated.
The earth rotates at 1000 miles per hour. We have planes that can go mach 3 which is around 2000 miles per hour.
Not all rockets go this fast. The kind of rockets that launch fireworks don't move that fast, but some military rockets and space going rockets are faster than the Earth.

Earth's average orbital speed is 29784.7 meters per second. The escape speed from the solar system, starting at a distance 1 astronomical unit from the sun, is 42121.9 meters per second. There have been rocket payloads, such as Pioneer 10,11 and Voyager 1,2 that have left the solar system. But those probes got a boost from the Earth's orbital motion, and they got other boosts from the gravity of other planets. The rockets didn't provide all the energy necessary for those probes to fly into interstellar space.

If u r considering from stationary point earths speed is around 30km/s & rockets has merely reached the speed half of it, but relative speed of earth to rocket can varied by launching it in direction of earths revolution or opposite but this doesnot happen coz earths gravity makes all the objects on earth to move with the speed at which it moves(30km/s) so technically even if u r not moving u will be at a speed of 30km/s.

Earth orbits the Sun at 66,000 MPH. The fastest rocket we have ever launched only goes about half that fast. Of course if the rocket is launched from Earth at 33,000 MPH in the space direction as Earth, it may be going "only" 33,000 MPH as seen from Earth but it is going 99,000 MPH as seen from the Sun.
