The bird that migrates the farthest is the Arctic tern. Each year, the Arctic tern travels 32 000 km between the Arctic Ocean and the continent of
Antarctica. Most of the migration takes place within two four-month periods
each year. Assume an Arctic tern completes the second half of its annual
migration distance in 122 days. Also assume that during this time the tern flies
directly north. If the tern flies the same distance each day, what is its velocity
in kilometers per day?
