If you start at the equator and travel to 10 degrees north latitude, approximately how many miles north of the equator will you be? take the circumference of the earth to be 24,900 miles. show calculations.

691.666 miles north of equator will be  

Explanation:

We have given circumference of the earth = 24900 miles

It is given that someone starts at the equator and travel to 10° north latitude

We know that if we complete one whole round of earth then we travel 360°

And we also know that 1 complete round is equal to the circumference of the earth

So in completing 360° we travel 24900 miles

So for 10° =

So 691.666 miles north of equator will be
