Answer:
S=32.5
W=97.5
Step-by-step explanation:
S=speed of plane in still air
W=speed of wind
-----------------------------------------
3(S+W)=130
6(S-W)=130
-----------------------------------------
S+W=43.33333...
S-W=21.66666...
2S=64.999...
S=32.5(simplified)
-----------------------------------------
32.5+W=130
W=97.5
-----------------------------------------
9 1/10 = 9.1
