254 days (approx.) to get to Mars, but a bit faster coming back to Earth as a spacecraft would be travelling into the gravitational pull of the Sun
About 2 years. Scientists say it may take 1 year to get to Mars
Mariner 4 went to Mars on Nov. 28, 1964 and came back to Earth on Jul. 14, 1965
It would take 6 to 8 months just to get there! So, in total, it would probably take a little over a year, there and back!
it took the mars pathfinder 211 days to get to mars.
Using current technology: it can take as little as 6 months and as long as a year to get to mars at optimum position
around 96 days
it take 5 years to build the mars ultor.

You can't.
It depends completely on the type of propulsion used to get to Mars.
