To find out how many times greater the diameter of IC 1101 is compared to the diameter of the Milky Way, you can divide the diameter of IC 1101 by the diameter of the Milky Way:
\[
\text{Ratio} = \frac{\text{Diameter of IC 1101}}{\text{Diameter of Milky Way}} = \frac{5 \times 10^{22} \text{ meters}}{1 \times 10^{21} \text{ meters}}
\]
Calculating this gives:
\[
\text{Ratio} = \frac{5}{1} \times \frac{10^{22}}{10^{21}} = 5 \times 10^{1} = 50
\]
So, the diameter of IC 1101 is about 50 times greater than the diameter of the Milky Way.
The correct answer is **d. 50**.
\[
\text{Ratio} = \frac{\text{Diameter of IC 1101}}{\text{Diameter of Milky Way}} = \frac{5 \times 10^{22} \text{ meters}}{1 \times 10^{21} \text{ meters}}
\]
Calculating this gives:
\[
\text{Ratio} = \frac{5}{1} \times \frac{10^{22}}{10^{21}} = 5 \times 10^{1} = 50
\]
So, the diameter of IC 1101 is about 50 times greater than the diameter of the Milky Way.
The correct answer is **d. 50**.
