Stacy is painting her bedroom. She is able to paint §
- of the bedroom in 3 hours. At this
rate, how long will it take her to paint the entire room? (1 point)
§ hours
4
• 4 hours
• 12 hours
• 6 hours
Since Stacy is able to paint § of the bedroom in 3 hours, we can assume that she can paint the entire room in 4 times that amount of time. Thus, it will take her 4 hours to paint the entire room.
Miguel is returning from a trip. In 4 hours, he has driven ? of the total distance. He
wants to know how long the total drive will take. At this rate, what is the total time it will take him to reach his destination? (1 point)
• 8 hours
§ hours
• 12 hours
• 6 hours
If Miguel has driven § of the total distance in 4 hours, we can assume that he will need 4 times that amount of time to complete the entire drive. Therefore, it will take him 16 hours to reach his destination.
Iris is asked to sweep the gymnasium floor after a basketball game. This requires her to push a sweeper from one end of the gym to the other and repeating the pattern until she has covered the entire floor. She completes 2 of the floor in I of an hour.

It takes Julian | hour to walk 2 miles. He decides to start walking in his spare time, but because he wants to make sure he has enough time to go a desired distance he created the
data table. At which ratio does the constant of proportionality appear?
(1 point)
O (4, 1)
o (1, =)
o (1, 4)
0 (;, 1
The ratio at which the constant of proportionality appears is (1, 2). This is because in the table, for every 1 hour that Julian walks, he walks 2 miles.
Ruth can read 15 pages in 30 minutes. She decides to create a table to keep track of her progress. From the data provided, at what ratio is the constant of proportionality?
(1 point)
• (1, 30)
• (15, 1)
• (2, 60)
• (1}, 30)
The ratio at which the constant of proportionality appears is (15, 1). This is because for every 15 pages that Ruth reads, it takes her 1 unit of time, which in this case is 30 minutes.
Determine if the quantities in the data table re in a proportional relationship. If they do not have a proportional relationship, indicate why.
(1 point)
• No, the ratios are not equivalent.
• No, the table does not count consecutively.
• Yes, the data table has a proportional relationship.
No, the ratio 7: 35 is not proportional to the other ratios.
