When a plane flies with the wind, it can travel 1575 miles in 3.5 hours. when the plane flies in the opposite direction, against the wind, it takes 4.5 hours to fly the same distance. find the average velocity of the plane in still air and the average velocity of the wind?

Now by the above two equations we will have
