An airplane is flying from dallas, texas to pensacola, florida. flying at maximum velocity, it encounters strong winds moving at half the speed of the plane in the opposite direction. how long will it take the plane to arrive in pensacola, relative to the original arrival time?
f. it will take half the time.
g. it will take twice as long.
h. it will take 1.5 times as long.
i. it will take three times as long.

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.

the answer would most likely be c, because if it's a comical piece of information, it may likely not be true, if it's a site that allows anybody to edit the content, it could mean a five year old is typing the info, and if it's a tv show produced by a celeb, it may have a biased opinion.
