    Answer:

    74.25feet

    Step-by-step explanation:

    Given the scale of a model train expressed as;

    1in = 13.5feet

    We are to express length of 5.5in in feet

    5.5in = x

    Divide both expressions

    1/5.5 = 13.5/x

    Cross multiply

    1×x = 5.5× 13.5

    x = 74.25feet

    Hence the actual length of the car in feet is 74.25feet
