The Starship Enterprise, apparently escaping from the clutches of Cthulhu (the image was not altered, this is how it was given!) is flying to the moon at a velocity of 0.7c.

How long will it take (in seconds) for it to get to the moon, as observed from the Earth's frame of reference.

D from Earth to the Moon is 384,000 Km.

At t=0 the ship is over the earth

2. Relevant equations

Time=distance/speed...

3. The attempt at a solution

Am I wrong to assume this has nothing to do with relativistic time dilation or shortening of distances and what-not?

This seems to be a straightforward calculation.

So is this right:

384,000 Km = 3.84*10^8 m

c = 3*10^8 m/s

[tex]\frac{3.84*10^8}{0.7*3*10^8}[/tex] = 1.828571428 seconds.

I got this in a relativity assignment so I'm suspicious of this solution.

If I missed something please let me know.
