I'm glad to help you. I am a Chinese student and I think there's something different between our classes. :)
let the speed of the helicopter in still air = x
let the wind speed = y

then you can get a linear equation of two unknowns.
2�(x-y)=264 [upwind flight distance ]
2�(x+y)=396 [downwind flight distance]
then solve it.
Okay.
