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/hkm/h. One such bird is flying at 100 km/hkm/h relative to the air, but there is a 46.0 km/hkm/h wind blowing from west to east.
Part B
How long will it take the bird to cover a ground distance of 500 kmkm from north to south? (Note that even on cloudy nights, many birds can navigate using the earth's magnetic field to fix the north-south direction.)
