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)

Based on the information provided, Mars is about 140 times farther away from Earth than the moon. Therefore, it would take the same spaceship approximately 140 times longer to reach Mars than it took to reach the moon.

Since it took the spaceship 3 days to reach the moon, it would take approximately 140 times 3 days to reach Mars.

Calculating:

3 days * 140 = 420 days

Therefore, it would take the spaceship approximately 420 days, or about 1 year, to reach Mars.
