A light-year is a unit used to measure large distances in space. One light-year is approximately equal to 5.88 trillion miles. On a map of the Milky Way Galaxy, the scale is 1 inch:70 light-years. If two stars on the map are 19 inches apart, about how far apart are they in the galaxy?

Answers

Answer 1
Answer:

Answer:

7.8204* 10^(15)\ \text{miles}

Step-by-step explanation:

In the map the scale is

1\ \text{inch}=70\ \text{light-years}

So

19\ \text{inches}=19* 70=1330\ \text{light-years}

In miles

1\ \text{light-year}=5.88* 10^(12)\ \text{mi}

1330\ \text{light-years}=1330* 5.88* 10^(12)=7.8204* 10^(15)\ \text{miles}

The galaxies are 7.8204* 10^(15)\ \text{miles} apart.
