I have been asked to work out the distance a package has travelled in 5 days if it is travelling 0.909090901c the speed of light.(adsbygoogle = window.adsbygoogle || []).push({});

I know its a simple question but there is a twist i dont get. I worked out

0.909090901/c = 30303030.03 m/s (that is the package is travelling at 30303030.03 m/s )

I then worked out there were 432000 seconds in 5 days so just multiplied them together to get 1.309090897*10^{13}metres.

Which i am happy with. It then asks me to state it in terms of light days....this is where i am stuck.

Any help?

It then asks how long a package travelling the same distance but at a velocity of 0.8035714286c takes. I think i am supposed to do t=d/v but this just gives me a stupid number.

ANy help with this too?
