a
Given that the distance from New York to Chicago is and the speed of the plane is we will use the given equation to find the time for the trip.
Solve for
The trip takes about hours.
b
Let's first find the time of the return trip by subtracting from The return trip took hours. We will now determine the speed of the plane on the return trip. Since it helps the plane to move faster, the plane's speed can be expressed as shown below. Note that the distance is still miles. Finally, to find the value of we can substitute the values into the equation
The speed of tail wind is
