Canada 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. The one goose is flying at 100 km/h relative to the air but a 36 km/h wind is blowing from west to east.
1) 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?
2) How long will it take the bird to cover a ground distance of 450 from north to south?
