Question During the 1960s and 1970s, The Apollo spacecraft took humans to the Moon in three days. Traveling to Mars requires a trip of around 2 AU in total. How long would this trip take, traveling at the same speed as to the Moon?

Solution Distance to Moon is approximately $380\cdot 10^{3}$ km. 2 AU is approximately $300\cdot 10^{6}$ km. Difference in 789.5 times. So, if it took them 3 days to get to the Moon, with the same speed getting to Mars will take them $3\cdot 789.5=2368.5$ days.
