If a spaceship can reach the moon in 3 days, how long will it take to reach Mars knowing that Mars is 140 times farther away from Earth than the moon is?

Answer 1

If a spaceship can reach the moon in 3 days, and Mars is 140 times farther away than the moon, you can calculate the time it would take to reach Mars by multiplying the time to reach the moon by the distance factor.

Time to reach Mars = Time to reach the Moon × Distance factor Time to reach Mars = 3 days × 140

Calculating that gives:

Time to reach Mars = 420 days.

So, it would take 420 days to reach Mars.
