Answer:
<h2>The speed of the airplane is 475 miles/hour and the wind is 25 miles/hour.</h2>
Step-by-step explanation:
Let, the speed of the airplane is x miles/hour and the wind is w miles/hour.
With the wind, the speed will be (x + w) miles/hour and against the wind, the speed will be (x - w) miles/hour.
As per the given question, or, w = x - 450.
Now, .
Thus, w = 475 - 450 = 25.
Well, there are 12 inches in one foot, so what does that tell you? :)
