Question

What is the approximate speed at which the earth orbits the sun?

Answer 1

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.
