Explanation:
It is given that,
Speed of the jet airplane with respect to air,
If the wind at the airliner’s cruise altitude is blowing at 100 km/h from west to east,
(A) Let is the speed of the airliner relative to the ground if the airplane is flying from west to east,
(B) Let is the speed of the airliner relative to the ground if the airplane is flying from east to west,
Hence, this is the required solution.
