We call this "retrograde" motion. It is caused by the fact Mars is in an orbit farther out from the Sun than Earth is, but Earth and Mars are both circling the Sun. So every time the Earth starts to catch up to Mars and then PASS Mars, Mars "appears" to move backwards as we pass by.
Mars cannot orbit the earth. It orbits the Sun aprox. every 2 Earth years.
3o billion years
It doesn't take 3 years. The total journey time from Earth to Mars takes between 150-300 days depending on the speed of the launch, the alignment of Earth and Mars, and the length of the journey the spacecraft takes to reach its target.
THERE IS NO TIME ZONE ON MARS..... And since no one has ever set foot on mars there is no way to calculate time. When an unmanned spaceship arrives at Mars it is probably calculated to Houston (central) time.

Mars revolves on its axis once in 24.6229 hours.
it takes 1 day
687 earth days.
24hours and 37 minutes
If the Earth takes 1 year to orbit the Sun, Mars orbits the Sun in 1,8 years.
One Mars year.

i dont exactly know what you mean about the time
Because spacecraft don't travel in a straight line from Earth to Mars, as it would take too much energy. Instead they go on long eliptical transfers to meet up with where Mars will be at a later time.
