By looking through a small telescope, you can see stars that are 3{,}112{,}000{,}0003,112,000,0003, comma, 112, comma, 000, comma, 000 light-years away. Approximately how many times as far can you see using a small telescope as without any equipment?

Answer 1

Answer:

1111 times

Step-by-step explanation:

Without any equipment, you can see stars that are 2,800,000 light-years away.

Using a small telescope, you can see  stars that are 3,112,000,000 light years away.

To determine approximately how many times as far you can see using a small telescope as without any equipment, we divide the number of light years.

That is:

$\dfrac{\text{Distance Covered Using a telesope}}{\text{Distance Covered without any equipment}} =\dfrac{3,112,000,000}{2,800,000}\\=\dfrac{3112}{2.8} \\=1111.43\\\approx 1111$

Therefore, you can see approximately 1111 times as far using a small telescope as without any equipment.
