The driving distance is computable
The driving distance between the United States and Australia is computable, and there are a few ways to approach this calculation. One method is to use the Haversine formula, which determines the great-circle distance between two points on a sphere, in this case, the centres of the United States and Australia. This formula takes into account the latitude and longitude coordinates of both locations and provides a distance measurement.
Another approach is to consider the distance between specific locations in each country. For example, the distance from Sydney, Australia, to New York City, USA, can be calculated. This would involve measuring the distance by road and sea, taking into account the specific route chosen and the respective geographic centres of the two countries.
Additionally, one could consider the flight distance between the two countries, which is approximately 9,204.14 miles (14,812.63 kilometres) according to one source, while another source gives the distance as 9,437 miles (15,187 kilometres). This distance represents the shortest path between the two countries, often referred to as "as the crow flies".
