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 1 year
about 1 year
about 7.5 years
about 7.5 years
about 2.5 years
about 2.5 years
about 22.5 years
Help is here is 100% correct just like my quiz
the answer is 1 year
1) 630 cm
A human operated spaceship reaches the moon in 3 days…?
2) about 1 year
What is the main problem with this model if you were going to be used to study the dimensions of the solar system?
3) The planets are placed at the same distance from each other
Why do astronomers use astronomical units (AU) instead of kilometers (KM)
4) large distances are easier to express in AU then in KM
thanks @help is here
3*140 = 420 days
so ...
and stop duplicating your text.
so annoying
To find the approximate time it would take for the spaceship to reach Mars, we can use the information given about the distance between Earth and the Moon and the distance between Earth and Mars.
The moon is about 386,400 km from Earth, and Mars is about 140 times farther away than the moon. Therefore, the distance between Earth and Mars can be calculated by multiplying the distance between Earth and the Moon by 140.
386,400 km (distance to the Moon) * 140 = 54,096,000 km (distance to Mars)
Now, since we know that the spaceship took 3 days to reach the Moon, we can calculate the time it would take to reach Mars using a proportional relationship.
Distance to Mars / Distance to the Moon = Time to reach Mars / Time to reach the Moon
54,096,000 km (distance to Mars) / 386,400 km (distance to the Moon) = Time to reach Mars / 3 days
By solving this equation, we can find the approximate time it would take to reach Mars.
Time to reach Mars = (54,096,000 km / 386,400 km) * 3 days
Time to reach Mars ≈ 74 days
So, approximately, it would take that same spaceship about 74 days to reach Mars. Therefore, the correct answer is "about 2.5 years".
