The earth travels in a nearly circular orbit about the sun. The mean distance of the
earth from the sin is 1.5¡Á1011 m. What is the approximation speed of the earth in
its orbit around the sun?

Please type your subject in the School Subject box. Any other words, including obscure abbreviations, are likely to delay responses from a teacher who knows that subject well.

You know that it takes 365.25 days for the Earth to make a complete revolution around the sun. So, convert that to seconds and divide it into the circumference of the orbit.
The orbit's circumference is
2 pi*1.5*10^11 m
