Finding Geographical Longitude Of A Body

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)
