Monica stepped outside and began to think how fast she is moving even when she is standing still.
Assume that the earth is a sphere with a radius of 3960 miles and Monica is at a latitude of 13∘N.
What is Monica's speed due solely to the rotation of the earth in miles per hour?

at that latitude r = 3960 * cos(13)
so the speed is 2*pi*r/24 mi/hr
