The distance between the two planets is reported to be 7 x 10 km at the time of her journey. The shuttle moves at a constant speed throughout the journey and the shuttle companiy advertises that it mores so fast that 7 = 14 Ignore the effects of acceleration and the movement of the planets for this question (a) What is the speed of the shuttle, in terms of e? (b) What is the distance of the journey, according to Alice? (e) What is the duration of the journey, according to Alice? (d) What is the duration of the journey, according to Bob? (c) While Alice is on her way, another shuttle that is traveling in the opposite direction back to Earth goes past her. Assuming the other shuttle moves at the same speed as the shuttle Alice is on relative to the planets, what speed does Alice measure for the Earth-bound shuttle?
