A space station comprises of two donut-shaped living chambers, A and B, which encompass the radii 3.20 x10 ^2 m and 1.10 X10^3 m correspondingly. As the station rotates, an astronaut in chamber A is moved 1.51 x 102 m all along a circular arc. Explain how far all along a circular arc is an astronaut in chamber B moved throughout the same time?
