    Answer: 95 feet

    Step-by-step explanation:

    Let the length of the horizontal run be represented by x.

    Slope Grade = (Rise/Run) * 100

    20 = (19/x) * 100

    20 = 1900/x

    20x = 1900

    x = 1900/20

    x = 95

    Therefore, the length of the horizontal run must be 95 feet
