Question

Epsilon Eridani is a star that is 10.5 light years away from Earth. One light year is about 9.46 trillion kilometers. What is the distance between the star and Earth in kilometers?

A) 99.33 trillion kilometers
B) 89.29 trillion kilometers
C) 90.33 trillion kilometers
D) 100.37 trillion kilometers

Answer 1

The distance between Earth and Epsilon Eridani, which is 10.5 light years away, is calculated as 99.33 trillion kilometers by multiplying 10.5 by 9.46 trillion kilometers, the distance of one light year.

Step-by-step explanation:

The question asks to calculate the distance between Earth and the star Epsilon Eridani, which is 10.5 light years away. Using the information that one light year is approximately 9.46 trillion kilometers, we can find the distance in kilometers by multiplying the number of light years by the distance of one light year:

Distance = 10.5 light years × 9.46 trillion kilometers/light year

Distance = 99.33 trillion kilometers

Therefore, the correct answer is A) 99.33 trillion kilometers.
