Question 1156630
-------------------------
The speed of the wind is 20 miles per hour. If it takes a plane 7 hours to fly 2368 miles round trip, determine the plane's speed in still air.
---------------------------


With wind one way and against the wind the other way?

<pre>

              SPEED          TIME           DISTANCE

AGAINST        r-20          2368/(r-20)       2368

WITH           r+20          2368/(r+20)       2368

TOTAL                          7
</pre>


This is too much like another solved not too long ago.
