When the Mars and the Earth are at the opposite sides of the Sun, the distance is the largest: approximately: 378 million km. The time needed for an electromagnetic wave to cover this distance is approximately: 21 minute. The closest distance between Mars and Earth is 78 million km, the time in this case is: 4.3 min.So the time of travel between Earth and Mars is between 4.3 minutes and 21 minutes, depending on the actual distance between the two planets.he time needed for an electromagnetic wave to cover this distance is approximately: 21 minute. The closest distance between Mars and Earth is 78 million km, the time in this case is: 4.3 min.
