    1.
    longer piece ---- x
    shorter piece ----(2/3)x

    x+ 2x/3 = 40
    3x + 2x = 120
    5x=120
    x=24

    long piece is 24 , short piece is 16

    2. speed of plane in still air --- x mph
    speed of wind ---- y mph

    9(x-y) = 540 ---> x-y = 60
    6(x+y) = 540 ---> x+y = 90

    add them:
    2x = 150
    x = 75

    speed of plane: 75 mph
    speed of wind : 15 mph
