Answer: 2,073Explanation:1) Circumference of the Earth:Circumference = 2π x radius
⇒ Circumference = 2π × 3959 miles = 24,875.13 miles
2) Distance between San Antonio and the Equator.Note that that distance corresponds to the arc length of a sector of 30°.
That let's you to set the
proportion:
From which you can
clear the unknown:
x = 30 × 24,875.13 / 360 = 2,072.93
Which rounded to the neares mile is 2,073
