A human-operated spaceship reaches the moon in 3 days. The moon is about 386,400 km from Earth. Mars, our closest planetary neighbor, is, at its closest, about 140 times farther away from us than the moon if Mars stays in place. Assuming a very simple model of the solar system, about how long would it take that same spaceship to reach Mars?(1 point)

To calculate the time it would take for the spaceship to reach Mars, we can use the distance ratio between Mars and the moon. Mars is about 140 times farther away from us than the moon. Given that it takes 3 days to reach the moon, we can calculate the time it would take to reach Mars.
So, if the spaceship takes 3 days to reach the moon, and Mars is 140 times farther away, the time it would take to reach Mars would be:
3 days * 140 = 420 days
Therefore, it would take the spaceship about 1 year to reach Mars.
