Note that unlike the time taken to travel from Delhi to New York, the time taken to travel from Earth to Mars depends on when the journey is started.


To understand, here's a diagram of the solar system with just Earth and Mars on it. The inner orbit shows 3 positions for Earth - at a, b and c. The outer orbit shows Mars at 4 positions - A, B, C and D.



When Earth is at a, Mars is at A; and when Earth is at b, Mars is at B. Same for c and C.


Clearly, the time taken to travel from a to A is much longer than the time taken to travel when Earth is at b and Mars is at B.


There's another factor to take into account. Lets look at Earth at c and Mars at C. When the spaceship travels from c to reach Mars, the spaceship actually doesn't head towards C. It heads towards the rendezvous point - marked D in the figure. As the spaceship leaves c and heads towards D, Mars travels from C and reaches D at the same time the spaceship reaches the rendezvous point D.


Clearly, the time taken to travel from Earth to Mars depends on when the journey is started; and of course the speed of the spaceship.


Usually, launches to Mars try to leverage this and pick a time when the journey is shortest. There are windows of time when reaching the rendezvous point takes less time - scientists use this information to plan launches accordingly.

I am not the smartest but i believe it take 300 days to travel to mars. Sorry if this is wrong.

No answer is wrong as long as you support your answer with logical reasoning.

Depends on the speed you're traveling at.
