Answer: OPTION B.
Step-by-step explanation:
You need to analize the information given in order to solve this exercise.
According to the explained in the exercise, the graph shows Eli's distance (in miles) away from his house as a function of time (in minutes).
Then, based on that you can determine that he started his trip from the point 
(Notice that the time and the distance are zero)
Observe in the graph that he arrived to the library (which is 4 miles away from his house) after 30 minutes.
Then, he stayed at the library. You know this because it is represented with an horizontal line.
Now you can identify in the graph that, from the point 
,in which the time in minutes is 
, Eli began his trip from the library to his house.
Therefore, based on the above, you can determine that, when the time is equal to 120 minutes, Eli rode his bicycle home from the library.
Answer Step-by-step explanation:
Word (story) problems are easy if you use a table to translate the words to precise, concise math variables and operations. For example,
Is means =
Larger than +
Four times a 4*a
F is 550 less than S F = S – 550
Total of A, B, C A + B + C
This seems obvious – until you get stuck on a word problem. So,
“the first company” , “a second company” becomes Let their costs be F and S
Let K be the number of kilograms
“$20 to ship a medium box, plus an additional $2 per kilogram” F = $20 + 2*K
“10 for the same size of box, plus an additional $3 per kilogram” S = $10 + 3*K
“the two shipping methods will cost the same amount” F = S
“What is that weight?” report K
Now, the math:
F = S
20 + 2K = 10 + 3K
$10 = K
