A Spaceship from Another Galaxy Passes Over the Solar System $\gamma$

Multiple Choice

A spaceship from another galaxy passes over the solar system directly above a radial line from the sun to the Earth.(We measure that distance to be 1.5 *10¹¹ m. ) On Earth,the spaceship is observed to be traveling at a speed of 0.80 c,for which $\gamma$ = 5/3.As measured on Earth it takes the spaceship 625 seconds to travel from the sun to Earth.When a scientist in the spaceship measures the Earth-sun distance and the time it takes her to travel that distance,she finds the results are respectively

A) 9.0 *10¹⁰ m;375 s.
B) 9.0 *10¹⁰ m;625 s.
C) 1.5 * 10¹¹ m;625 s.
D) 2.5 * 10¹¹ m;625 s.
E) 2.5 *10¹¹ m;1042 s.
