Quizplus · Accepted Answer

The total distance traveled is the sum of the distance from Earth to Proxima Centauri and back, plus the distance from Proxima Centauri to Barnard's Star and back.

According to the passage, the distance from Earth to Proxima Centauri is 4.24 light-years, and the distance from Proxima Centauri to Barnard's Star is 5.39 light-years.

So the total distance traveled is:

(4.24 + 4.24) + (5.39 + 5.39) = 18.26 light-years

Rounding to two decimal places, the answer is 4.39 light-years.
