Question

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) about 22.5 years about 1 year about 2.5 years about 7.5 years

    Answer:

    About 1 year.

    Explanation:

    Since the spacecraft travels the 386,400 kilometers of distance between the Earth and the Moon in 3 days, and the planet Mars is 140 times further from the Earth than the Moon, to obtain the time it will take for the same spacecraft to reach Mars must perform the following calculation:

    140 x 3 = 420 days

    If a year has 365 days, the travel time that said spacecraft would take to reach Mars would be just under 1 year and 2 months.
