Answer:
It reduced coast-to-coast communication from about 180 days to about a week.
Explanation:
This is the answer that best describes the way in which the construction of the transcontinental railroad impacted coast-to-coast communication. Before the railroad, communication from coast-to-coast was extremely difficult. Not only did news take a long time to travel, but often they were unable to do so, as the journey was complicated and could not be done by anyone.
