How does it take to get to mars

Your question is answered.

Presumably you mean Cylero. Assuming you've got the basics down (building rockets, launching, and performing orbital maneuvers) there are a couple of good tutorial videos out there for performing basic interplanetary transfers. This one is specific to SimpleRockets 2 and going from Droo to Cylero. It's a little muddled but it demonstrates the concept. Then there's this video from none other than Scott Manly that does a great job explaining the fundamentals, so I highly recommend it even though it's a tutorial for Kerbal Space Program.

As far as where to start, here is the short version of the steps involved:

1. Build a rocket with at least 10.5 km/s Delta V (more if you want to land on Cylero, way more if you want to come home again).
2. Get into a circular "parking orbit" around Droo (~100km altitude is good).
3. Wait until a line from Cylero to Juno (the sun) to Droo makes a ~45 degree angle, and Droo is behind Cylero in its orbit (see Hohmann Transfer).
4. Create a burn node ~10 degrees into the dark side of Droo, and increase the prograde Delta-V until it is enough to escape Droo and gets you on an elliptical orbit that reaches Cylero's orbit (If you can get an encounter, meaning the closest approach indicator turns green, thats great, if not you can correct later). Execute that burn.
5. Wait until you are out of Droo's sphere of influence.
6. Find your ascending node, create a burn node at that point and adjust your inclination until you will be at the same elevation as Cylero when your orbit's cross.
7. If you don't yet have a rendezvous, tweak the burn using all three axises until you do (this is an art, or a lot of math, I cannot dictate simple steps).
8. Ideally, your rendezvous gives you a parabolic orbit with a low periapsis.
9. Wait until you are in Cylero's SOI.
10. Create a burn node at your periapsis, and add Delta-V retrograde until you get an orbit you're happy with. Execute that burn.

If you watch the videos and still need help given that, you'll need to be a little more specific about which steps you need help with.
