Homework Statement
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

Homework Equations
Time=distance/speed...
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.*can't edit the title, obviously should be "have"...
