    Answer: on the first day, they hiked 9 miles.

    On the second day, they hiked 16 miles.

    Step-by-step explanation:

    Let x represent the distance that the two hikers hiked from the first mountain to the second mountain.

    Let y represent the distance that the two hikers hiked from the second mountain to the hollow.

    The total distance is 25mi. This means that

    x + y = 25 – – – – – – – – – – – – – -1

    If the distance between the second mountain and the hollow is 7mi more than the distance from the first mountain to the second mountain, it means that

    y = x + 7

    Substituting y = x + 7 into equation 1, it becomes

    x + x + 7 = 25

    2x = 25 – 7

    2x = 18

    x = 18/2 = 9

    y = x + 7 = 9 + 7

    y = 16
