Astronomers measure large distances in light-years. One light-year is the distance that light can travel in one year, or approximately 5.88 × 10^12 miles. Suppose a star is 9.8 × 10^1 light-years from Earth. In scientific notation, approximately how many miles is it?

Final answer:

The distance in miles for a star that is
9.8 × 10^1 light-years away is approximately
5.75 × 10^13 miles.

Step-by-step explanation:

A light-year is the distance that light travels in one year.

It is approximately
5.88 * 10^12 miles.

To find the distance in miles for a star that is
9.8 * 10^1 light-years away, you can multiply the number of light-years by the number of miles in one light-year.

So, the distance in miles is -


= 9.8 * 10^1 * 5.88 * 10^12


= 5.75 * 10^13
