It is 30 kilometer per second.

#### Explanation:

The earth goes round in 365.242 days.

The average radius of earth's orbit is 149.10 million kilometers.

so circumference can be calculated.

circumference is Pi x Diameter..Pi=3.1428

2x149100000=d.

365.242 days convert into seconds.

365.242 x 24 x 3600

distance divided by time will give speed.
