Answer:
The jet stream, which helps to speed it up and makes the flight shorter.
Explanation:
The correct answer is C. jet stream. Jet streams are high-speed winds that flow in the upper atmosphere, typically at altitudes between 10 and 15 kilometers. They are caused by differences in temperature between the equator and the poles, and between the land and the oceans. These winds can reach speeds of up to 400 km/h and can have a significant effect on the speed and direction of airplanes flying at high altitudes.
In the case of the question, the jet stream is flowing from west to east, which means that the airplane flying from Seattle to Boston is flying against the jet stream, which slows it down and makes the flight longer. However, on the return trip from Boston to Seattle, the airplane is flying with the jet stream, which helps to speed it up and makes the flight shorter.
