The other 3 is in the 100's place and it's value is 3 one hundreds or 300. So that is your digit... the 3 in the hundreds place.
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
