A pilot can fly 2070 miles with the wind in the same time she can fly 1840 miles against the wind.
If the speed of the wind is 10 ​mph, find the speed of the plane in still air.
~~~~~~~~~~~~~~~~ 

Write the "time" equation, saying that travel times are the same in both trips


    2070%2F%28x%2B10%29 = 1840%2F%28x-10%29


    2070*(x-10) = 1840*(x+10)


Now simplify it step by step, until you find x, the speed of the plane in still air.

At this point, you have all necessary instructions to complete this simple job on your own.
