The President is giving a speech about rising fuel costs. Suddenly he has a great idea. He announces that he is making a new law to cut down on gasoline usage. Each American household will be restricted to 40 gallons of gasoline per week. The President says the new rule will take effect immediately

That means that in 365 days,or one year each American family would have used 2,080 gallons of gasoline because 40x52 (there are 52 weeks in a year) =2,080 gallons each year. Also I don't know what you want to ask, but this is my best answer.

The transcontinental railroad provided a means of fast transportation. it cut a 6 month trip into 6 days, created jobs for many people and encouraged immigration. the homestead act played a huge role in western expansion; it allowed settlers to begin a fresh start, and gave them land in exchange for their residence for up to five years and a small fee.
