Explanation:
The Earth is travelling at its fastest at perihelion around 4 January. It is travelling at about 30.27 km/s.
The Earth is travelling at its slowest at aphelion around 4 July. It is travelling at about 29.29 km/s.
The average speed is about 29.8 km/s.
Over that last few years perihelion speed has varied between 29.29 and 29.3 km/s and aphelion speed has varied between 30.27 and 30.3 km/s.
The actual times of perihelion and aphelion and the orbital speed vary slightly from year to year due to the gravitational pull of the Sun, Moon and other planets.
