I agree with the other person. The answer is C 5 which can be shown in the diagram below.
The red outlines mark these blocks. Note that the upper two red blocks in the far right portion are underneath a set of blocks that are on the second story of this "building" of sorts.
W=wind p + w=158...p=158-w p-w=112...p=112+w SO 158-w=112+w 46=2w 23=w SO in conclusion you have the correct answer of wind being 23km/h while the plane is going 135 km/h
