Question 189037: The longitude of a geographic location is measured in the degrees east or west from the prime meridian (o) to the international dateline (180). Quito, Ecuador on the west coast of south america, has a longitude of 78.5 west. Singapore, on the Malay Peninsula in Asia, has a longitude of 104 east. Both cities are very close to the equator (assume they are on the eqautor for this problem). The diameter of the earth at the equator is 7928 miles. What is the shortest distance from Quito to Singapore? explain how you got your answer

;
We know that 1 degree of longitude = 60 nautical mi at the equator
:
Change 104 degrees east to degrees west
360 - 104 = 256 degree west
:
256 - 78.5 = 177.5 * 60 mi = 10,650 nautical miles from Quito to Singapore
:
That's  * 10650 = 12,102 statute miles
