    Joan’s remaining distance is reduced by (600 ft)/(3 hours) = 200 ft/hour. She starts with 1600 ft remaining, so her distance remaining (y) after x hours is
    .. y = -200x +1600

    In order for the distance remaining to be zero, you must have
    .. 0 = -200x +1600
    .. 200x = 1600
    .. x = 1600/200 = 8

    It will take Joan 8 hours to hike 1600 ft.

    Answer:

    Joan’s remaining distance is reduced by (600 ft)/(3 hours) = 200 ft/hour. She starts with 1600 ft remaining, so her distance remaining (y) after x hours is

    .. y = -200x +1600

    In order for the distance remaining to be zero, you must have

    .. 0 = -200x +1600

    .. 200x = 1600

    .. x = 1600/200 = 8

    It will take Joan 8 hours to hike 1600 ft.
