Answer:
G. It will take twice as long.
Explanation:
Let's call 
the original speed of the plane and 
the distance between Dallas and Pensacola. The time the plane originally takes to complete the flight is
In this problem, we are told that the plane encounters wind moving at half of its speed: 
, in the opposite direction. This means that the new speed of the plane is
And so, the time the plane takes now to complete the flight is
So, the plane takes twice the time as before.

It's the angle made by the incident ray when it's perpendicular to the surface. (Perpendicular lines are the lines that form a graph or like a 90-degree angle)
