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? Found 3 solutions by Alan3354, Boreal, MathTherapy:Answer by Alan3354(69443) (Show Source):
You can put this solution on YOUR website! Find the 2 groundspeeds, upwind and downwind
----
The plane's airspeed is the average of the 2.
==========
Windspeed is the difference between airspeed and groundspeed.
You can put this solution on YOUR website! speed = distance/time =245/7/6 hours=210 mph against wind
on way back 245/5/6 hours or 294 mph
294=p+w plane+wind
210=p-w plane - wind
add them
504=2p
p is 252 mph in still air
speed of wind is 42 mph.

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: . 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?
