On the global grid, a location 20° north of the equator and 30° west of the
prime meridian would be:

a. 130° west, 70° north.

b. 20° north, 30° west.

c. 130° west, 25° north.

d. 30° west, 20° north.

B. 20° north, 30° west

Explanation:

According to international convention, locations east of the Prime Meridian have positive longitudes while any point west of the Prime Meridian and before the International Date Line has a negative longitudinal value.

An alternative notion for writing coordinates in the Western Hemisphere is replacing the negative signs with the words east and west to avoid the negative and positive symbols and any possible associated confusion.
