    Answer:

      18π m

    Step-by-step explanation:

    Let R represent the radius of the Earth.

    Person A travels a distance of …

      C = 2πr . . . . circumference of a circle of radius r

      distance A = 2πR . . . . . using the Earth radius for the radius

    Person B travels a distance of …

      distance B = 2π(R +9 m) = 2πR +18π m

    __

    Then the difference of the distances is …

      distance B – distance A = (2πR +18π m) -(2πR) = 18π m

    The difference in distance traveled is 18π m.
