Taking account of the distances and the winds, if a plane were to fly from New Delhi to Kolkata (to and fro) and another one from New Delhi to Pune (to and fro) at a constant speed, which trip would you expect to be completed quicker ? (No stoppage)
Answer: B
Both trips would take the same amount of time.
The chart puts Kolkata and Pune at the same distance from New Delhi, 1,200 km. A plane to Kolkata pushes against the easterly wind on the way out and is carried by it on the way back. A plane to Pune is carried by the wind on the way out and pushes against it on the way back.
So each round trip is 2,400 km with one leg into the 2 km/hour wind and one leg with it, at the same constant speed. The two trips are identical in every factor that affects time.
Choosing either city alone looks at only one leg of its round trip. 'Cannot be determined' is wrong because the distances and the wind effect are both given.
