A star is 40 light years from Earth.(adsbygoogle = window.adsbygoogle || []).push({});

(a) How far would you measure this distance to be if you travelled it in a spaceship moving at 1.00X10^8 m/s

(b) How long would the trip last (for you)?

Can someone please help me out with this question and what equations I should use to solve this, thanks in advance
