1. The problem statement, all variables and given/known data Canadian geese migrate essentially along a north-south direction for well over a thousand kilometers in some cases, traveling at speeds up to about 100 km/h . If one such bird is flying at 100 km/h relative to the air, but there is a 30.0km/h wind blowing from west to east. At what angle relative to the north-south direction should this bird head so that it will be traveling directly southward relative to the ground? I calculated this part, and was correct -- 17.5 degrees to the west of south. My question is part b: How long will it take the bird to cover a ground distance of 600 km from north to south? (Note: Even on cloudy nights, many birds can navigate using the earth's magnetic field to fix the north-south direction.) In Hours! 2. Relevant equations 3. The attempt at a solution I was able to calculate part A, however I do not know where to go with part B. Thanks!
