To find out how many times more miles of roadway Union Center has than Amanville, we can use the following formula:
\[ \text{Times more} = \frac{\text{Roadway in Union Center}}{\text{Roadway in Amanville}} \]
Plugging in the values:
\[ \text{Times more} = \frac{6.73}{62.7} \]
Now, we calculate:
\[ \text{Times more} = \frac{6.73}{62.7} \approx 0.107 \]
Now, rounding to the nearest tenth:
\[ 0.107 \approx 0.1 \]
Thus, Union Center has approximately 0.1 times as many miles of roadway as Amanville.
Note: Since the question asked for how many times more Union Center has than Amanville, it's generally interpreted as how many more times does Amanville have than Union Center. Therefore, it would make sense to say that Amanville has significantly more roadway compared to Union Center.
