The distance from City of London to Portobello is about 19,000 kilometers. A direct flight would take around 21 hours, but there aren't commercial routes between these cities.
The antipode can be calculated by understanding the geographic coordinates and applying simple formulas. We will use the following variables:
Step 1: Obtain the geographic coordinates of City of London
The DMS coordinates are: 51°30'46'' N 0°5'30.6'' W. Calculations are easier by using the decimal format, hence:
LatO = 51.5127907°
LngO = -0.09184°
Step 2: Calculate the latitude
LatA = - LatO = -51.5127907°
Since the latitude is positive (north direction), the antipode must be negative (south direction).
Step 3: Calculate the longitude
LngA = LngO ± 180° = -0.09184 + 180° = 179.90816°
Since the longitude is negative, we sum 180° to ensure the final value lies between (-180, 180). If it were the other way around, we would substract 180° for the same reason.
The antipode of City of London is located on coordinates (LatA, LngA) = (-51.5127907, 179.90816), or in DMS format: 51°30'46'' S 179°54'29.4'' E.
