Question 1135475
Against the wind a small plane flew 245 miles in 1 hour and 10 minutes. The return trip took only nothing50 minutes. What was the speed of the​ wind? What was the speed of the plane in still​ air?
<pre>These people who're attempting to help others with mathematics need to do a MUCH BETTER job of providing ERROR-FREE solutions. 
Note to @BOREAL: {{{system(matrix(1,1, "245/7/6" <> 210), and, matrix(1,1, "245/5/6" <> 294)))}}}. Do you NOT KNOW ANYTHING about PEMDAS, or BOMDAS?
Think about it!!!
And, on top of that, you claim to be a statistician, volunteer math tutor, and former substitute math teacher in public schools?
GOSH!! Are you kidding me?
