Answer:
25 percent
Step-by-step explanation:
Percent decrease = (original - new)/original * 100 percent

= 10/40 * 100 percent
= .25 * 100 percent
=25 %
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
