    Jet: 415 mph

    Wind: 25 mph

    Step-by-step explanation:

    If x is the speed of the jet in still air, and y is the speed of the wind, then:

    x + y = 1320 / 3 = 440

    x - y = 1170 / 3 = 390

    Solve the system of equations with substitution or elimination. Using elimination:

    2x = 830

    x = 415

    y = 25
