## Homework Equations

Circle Circumference Formula

## The Attempt at a Solution

What I started off with was that we traveled 10 degrees in 1 hour, right? That means 10 degrees of the planet as a "circle" is 1000km. Using this, we can calculate the circumference as 1000km * 36, right? Am I on the right track? Thank you.
