They sell it in $2.25 per kg

1 kg : 2.25
3.4 : 7.56
1 x 3.4= 3.4
so, 2.25 x 3.4= 7.56
Let x be the velocity of the wind, then
(310+x) = plane speed downwind
(310-х) = plane speed upwind
![\frac{185}{310+x} = \frac{125}{310-x} \\ 185(310-x)=125(310+x) \\ 57350-185x=38750+125x \\ 57350-38750=125x+185x \\ 18600=310x \\ x=60 \ mph](https://tex.z-dn.net/?f=%20%5Cfrac%7B185%7D%7B310%2Bx%7D%20%3D%20%5Cfrac%7B125%7D%7B310-x%7D%20%5C%5C%20185%28310-x%29%3D125%28310%2Bx%29%20%5C%5C%20%2057350-185x%3D38750%2B125x%20%5C%5C%2057350-38750%3D125x%2B185x%20%5C%5C%2018600%3D310x%20%5C%5C%20x%3D60%20%5C%20%20mph)
