Canadian geese migrate essentially along a north$-$

south direction for well over a thousand kilometers

in some cases, traveling at speeds up to about

$100k\frac{m}{h}.$ One such bird is flying at $100k\frac{m}{h}$

relative to the air, but there is a $34\mathrm{.}0k\frac{m}{h}$ wind

blowing from west to east.
