A space station consists of two donut-shaped living chambers, A and B, that have the radii shown in the drawing. As the station rotates, an astronaut in chamber A is moved 3.18 102 m along a circular arc. How far along a circular arc is an astronaut in chamber B moved during the same time?

dunno
3.18 x 10^2= 318

(Ra and Rb are missing from this problem which is needed to solve this.)

Take 318 x Ra/ Rb to get your answer.
