    Answer: B. 12,000 feet

    Step-by-step explanation:

    Given : The measure of Mary’s stride=  2 feet, 8 inches.

    We know that 1 feet =1 2 inches

    Then, the measure of Mary’s stride=  2+\dfrac{8}{12}\ feet

    =\dfrac{12(2)+8}{12}=\dfrac{32}{12}\ feet

    No,. of steps = 4500

    Then, Distance = No. of steps x Measure of Mary’s stride

    =4500\times\dfrac{32}{12}\\\\=375\times32=12000\ feet

    Hence, the  distance she will walk if she takes 4,500 steps=12000 feet

    Hence, the correct answer is B. 12,000 feet
