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.
