7 0

Explanation:

In 1 hour it travels (5x+2) miles.

In (x-3) hours it travels = (5x+2)(x-3)

= 5x(x-3)+2(x-3)

= 5x²-15x+2x-6

= 5x²-13x-6 miles.

chubhunter [2.5K]

In Afghanistan, Amir and Baba’s relationship is strained. Baba doesn’t fully accept Amir, he views him as different, and the lack of similarities he sees from himself to Amir make Amir seem like an outsider. For example, Baba is a strong, brave man, while Amir chows signs of cowardice in many aspects of his life. In Afghanistan, there is little to no communication between the two characters, and Amir must find comfort in Rahim Khan, instead of his own father.In America, all of this changes. This change in their relationship could be a metaphor for the change in Afghanistan, the change of cultures, or the internal change Amir will go through, but it is a change regardless. The first this we see change is Amir takes a much larger role in his father’s life. Now he must watch over his father, like when Baba destroys the gas station store, and when he eventually gets cancer. Amir’s accomplishments seem to make Baba more proud, also. Back in Afghanistan, they only time Baba was ever really proud of Amir was when he won the kite tournament, a feat that Baba was more interested in Amir winning than Amir was. But in America, Amir’s accomplishments, like graduating form high school and going to college, are looked upon highly by Baba. Lastly, the communication barrier between Amir and Baba is finally broken down, the two seem to be able to talk more freely to each other, and Baba seems to respond to Amir more openly then he ever would have in Afghanistan.
