We have a question on motion with the elements of distance, time taken and speed.
This question in particular is asking us for distance per unit time (in this case, hours).
We are required to find out how much distnace is covered in on hour and our approach will be as follows:

This right here just tells us that 4 hours, Madeline covered 180 miles and since her rate was constant (equal distances in equal times), then she also covered 45 miles in an hour.
Now we plot our number line.
Answer:
The best answer is C
Step-by-step explanation:
A is not correct because the total amount of people that participated is 300
B is no correct because the 75% would be more than 20
C is correct because 20% of 100 is 20
D is wrong because A has more people supporting raising it.
correct me if I am wrong.
7: The football traveled 90 yds total 50+40=90
8: Answer: yes because 12²=144 9²=81 add them and get 225 and 15×15=225
9: x=15ft a^2+b^2=c^2 8^2+b^2=17^2 b^2+64=289 b^2=225 b=15
10: The cat is 12 feet above the ground, and Peter has to put the base of his ladder 9 feet away from the tree because of mud. If we consider a right-angled triangle, in which the height is 12 feet, base is 9 feet.
