Most spacecraft travel to Mars by an eliptical transfer orbit called a Hohmann Transfer. This normally takes 8 months one-way, and can only be done once every 2 years from Earth. This is not the quickest way to Mars, but it is by far the cheapest, so this is the one used most often.
If you had lots of money and energy, then quicker journeys are certainly possible. In the future ion propulsion engines (already in use on some satellites, e.g. GOCE) could be used to theoretically drop journey times to 40 days.
"Curiosity", the latest Mars rover, was launched on November 26, 2011
and landed on Mars on August 5, 2012.
That's 8 months and 10 days, door to door.
about 6-7 months
eight month
About 250 days, but I haven't checked the exact number. (I guess you mean the Mars Exploration Rover mission.)
The mars rover is a robot sent to mars to take samples and pictures for scientists to analyse back on earth, for detailed information i suggest Wikipeia
There's no specific time limit for how long a rover can last on Mars. Accidents and mechanical failure can affect the ability of a rover to survive. The Opportunity rover has so far been working almost non-stop for seven years. Its twin rover Spirit has not been heard from in almost a year and may no longer be functional.

there is only one mars rover and NASA invented the mars rover.
As the Mars rover would be on the planet for a long time it would have to use solar energy alone to move around.
