Astronomers measure large distances in light-years. One light-year is the distance that light can travel in one year, or approxi

Semenov [28]

Answer:

Option B - $=8.4672\times 10^{13}$

Step-by-step explanation:

Given : Astronomers measure large distances in light-years. One light-year is the distance that light can travel in one year, or approximately 5,880,000,000,000 miles.Suppose a star is 14.4 light years from earth.

To find : In scientific notation, how many miles away a star is from earth?

Solution :

One light-year is the distance that light can travel in one year is = 5,880,000,000,000 miles.

In scientific notation, $5.88\times 10^{12}$ miles.

In 14.4 lights year the distance is $=14.4\times5.88\times 10^{12}$

In 14.4 lights year the distance is $=84.672\times 10^{12}$

or $=8.4672\times 10^{13}$

Therefore, Option B is correct.
