For one you have to find the circumference of the which is 3.14 times diameter then divide 5280 which is a mile by the circumference that would be the answer
for two you have to take 1920 which is the 80 times 24, then take the circumference of the earth and divide it by 1920

CosA=(21^2+23^2-25^2)/2*21*23
cosA=345/966
A=cos^-1(345/966)
A=69.08
