Question

Two light-years is equal to _____.

O 6 million miles
O 6 trillion miles
O 12 million miles
O 12 trillion miles

Answer 1

6 trillion miles

Step-by-step explanation:

There are 6 trillion miles in a light-year (approximately), so the distance we need to go is 6 trillion miles / light-year times 4 light-years, or 24 trillion miles. So, this trip would take 1.2 billion hours. There are 24 hours a day and 365.25 days per year, so this time in years is 137 thousand years.
