30° N and 80° E
80° S and 30° E
80° N and 30° W
80° N and 30° E

1. Travel due North 40°: Moving north increases latitude. Starting at 40° N and moving 40° further north results in a new latitude of 40° N + 40° = 80° N. The longitude remains unchanged. Intermediate coordinates: (80° N, 90° W).
2. Travel due East 60°: Moving east changes longitude. Starting at 90° W and moving 60° east means reducing the westward longitude value towards the Prime Meridian (0°). The new longitude is 90° W – 60° = 30° W. The latitude remains unchanged. Final coordinates: (80° N, 30° W).
– Movement purely east or west changes only longitude (assuming travel along a latitude line, though the question specifies ‘due East’ implying change in longitude).
– Longitudes West of the Prime Meridian are typically negative or marked ‘W’. Moving East from West longitudes reduces the westward value.
