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.

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?
