Answer:
12.4 miles, N84.4°E
Step-by-step explanation:
Split the translation over the components parallel to the direction S>N and W>E, then calculate the sum of both components, and get magnitude and direction of the movement. Here's my calculation, double check them regardless.
For the first hour, it travels north and east. Once the wind changes, it flies "north" ( the actual movement is southbound, which will appear calculating the cosine and getting a negative number) and . The complete movement is 1.2 miles N and 12.3 miles E. The total movement is, with the Pythagorean theorem, 12.4 miles total, and the angle it forms with the north direction is the .
