    Flies to East with 150-30=120Kn, to west with 150+30=180Kn.
    Time to east =x min, Time to west=y min. x+y=180min.

    Equation: x·120Kn=y·180Kn  Substitute for y=180min-x

    x·120=(180min-x)·180
    120x=1802-180x
    300x=1802
    x=1802/300=108min.
    Distance to east after 108min flying= 108/60x120=216mile

    Nice Christmas from
