<span>It reduced coast-to-coast communication from about 180 days to about a week.
This question is mildly ambiguous due to the word "communication". Does it mean "Speed of sending a message?" or "Speed of moving a physical object?" Given the available options as answers, I will assume the meaning is "Speed of moving a physical object?" With that in mind, let's look at the available options and see what makes sense.
It made coast-to-coast communication instantaneous.
* Even modern jets can't travel from coast to coast instantaneously, so you wouldn't expect a train to do so either. So this choice is just plain silly and therefore wrong.
It reduced coast-to-coast communication from about a week to about a day.
* A stagecoach had an average speed of about 5 mph and covered 60 to 70 miles per day. So it's not going to go from coast to coast in only a week. And since that part of the answer is wrong, this choice is wrong.
It reduced coast-to-coast communication from about 180 days to about a week.
* The 180 day estimate is definitely doable. That's an average speed of about 17 miles per day which is a good speed for a person walking day to day. And that would be about 400 miles per day for the train. The numbers make sense and this is the correct answer.
It made coast-to-coast communication more complicated.
* Let's see. Buy a train ticket and possibly arrange for 6 layovers. Or plan a multiple month trip and possibly coordinate that effort without having any rapid means of communications? This option is just plain silly when you consider the logistics of traveling for several months vs traveling for a mere week. So this is a bad choice.</span>
Because United States of America is not a world country
Answer:
If Spain colonized Americs before we did then life could be way different. There wouldn't be a Revolutionary war or a Civil War. Spain would be more powerful cause of all of that land that they would have. Maybe they wouldve been no match for the Indians and the Indians may have fought all of them off. All of us today most likely would not be speaking English and would be Spanish witch would be wild. This is how life would be different if Spain took America over first.
