1. The problem statement, all variables and given/known data Find the distance between Helsinki and Seattle along the shortest route. Where is the northermost point of the route, and what is its distance from the North Pole? The longitude of Helsinki is 25ºE and latitude 60º; the longitude of Seattle is 122ºW and latitude 48º. Assume the radius of the Earth is 6370km 2. Relevant equations 3. The attempt at a solution I already solved the first part of the problem (the distance), which is 7640km, using spherical trigonometry, but I have no idea how to solve the second part of the problem.
