Final answer:
The speed of the wind is approximately 56.8 mph.
Step-by-step explanation:
To find the speed of the wind, we can set up two equations based on the given information. Let's assign a variable to the speed of the wind, let's say w:
Plane's speed with the wind = Plane's speed in still air + Speed of the wind
Plane's speed against the wind = Plane's speed in still air - Speed of the wind
Substituting given values into the equations, we get:
550 + w = 3498/t
550 - w = 3102/t
Next, we can solve this system of equations to find the value of w, the speed of the wind.
First, we can solve the second equation for t:
t = 3102/(550 - w)
Substituting this expression for t into the first equation, we get:
550 + w = 3498/(3102/(550 - w))
Simplifying this equation, we get:
w = 625/11
So, the speed of the wind is approximately 56.8 mph.
