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.
Mars is so far away in fact that it takes radio signals quite a long time to get from the spacecraft back to Earth. During Curiosity EDL, this delay will be 13 minutes, 48 seconds, about mid-way between the minimum delay of around 4 minutes and the maximum of around 24 minutes.
