What is the geographical longitude of a body whose GHA is 149° 30'?
Given:
GHA = 149° 30'?
What is asked?
Geographical longitude of a body
Solution:
You can make a diagram to solve this kind of problem. But I think it's much better to just memorize the rule in answering questions like this because it's faster, thus you can save time during your board examination.
So here's the rule:
If GHA is less than 180° ; the longitude is equal to GHA and is named "west".
GHA < 180° ; GHA = Longitude (W)
If GHA is greater than 180° , you have to subtract GHA to 360° , and the result will be the longitude and is named "east".
GHA > 180°
360° - GHA = Longitude (E)
