    Answer:

    648mph and 72 mph

    Step-by-step explanation:

    velocity Against wind=2880/5=576Mph

    velocity with the wind =2880/4=720mph

    let x be speed of plane y be speed of wind

    then velocity with winf=720

    x+y=720

    velocity against the wind=576

    x-y=576

    using both

    2x=1296

    x=648mph

    and y=72mph
