Question

from boston to seattle you are flying into the jet stream. from boston to seattle you are flying with the jet stream. from seattle to boston you are flying into the jet stream. from seattle to boston you are flying with the jet stream. why can flying from seattle to boston take less time than flying from boston to seattle in the same aircraft?

Explanation:

Jet streams generally flow from west to east in the Northern Hemisphere. When flying from Seattle to Boston (eastward), the aircraft is flying with the jet stream, which provides a tailwind, increasing ground speed and reducing travel time. Flying from Boston to Seattle (westward) would be flying against the jet stream (headwind), increasing travel time. The correct option is the one where the direction is Seattle to Boston and flying with the jet stream.

Answer:

From Seattle to Boston you are flying with the jet stream.
