Ending Amount = Beginning Amount / 2^n
where 'n' = # of half lives
n = 20,000 / 1,600 = 12.5 half-lives
Ending Amount = 1 kg / 2^12.5

Answer:
268,447,489 years
Step-by-step explanation:
We can use dimensional analysis to solve this problem.
There are approximately 5.879 x 10^12 miles/ light year
Therefore, 4 Ly (5.879 x 10^12 miles / Ly) = 2.3516*10^13 miles.
We are given a speed of 10 miles/hr
So, 2.3516 x 10^13 miles (1 hr/10 mi)(1 day/24 hrs)(1 yr/365 days) = 268447488 years or 2.684 x 10^8 years.
