The average amount of time it would take to reach Mars is 162 days, but the reality is different because the craft cannot pass through the sun. Accurate times require knowledge of fuel requirements and complex gravitational equations.
So, why does it take so long? If Mars is only 55 million km away and if a spacecraft can travel at 20,000 km/hour, you would expect the journey to take only 115 days, but it actually takes much longer. You can't just point your spacecraft at Mars and start firing your rockets. Because by the time you got there, Mars would have moved.
