If one traveled along the circumference of the equator, he will go 4003040030 kmkm - to the nearest kilometer.

Explanation:

Assuming questioner is referring to earth and its known radius is 63716371 kmkm and that it is a perfect circle at equator with this radius,

As circumference of a circle is given by 2pir2πr

If one traveled along the circumference of the equator,

he will go 2pixx6371=2xx3.14159xx6371=40030.142π×6371=2×3.14159×6371=40030.14 kmkm or to the nearest kilometer, it would be 4003040030 kmkm.
