The table below shows the number of math questions completed by Olivia with respect to time.
Math Questions 12 16 20 24 28
Time (minutes) 36 48 60 72 84
Which of the following statements gives the unit rate?
The unit rate can be calculated by dividing the number of math questions completed by Olivia by the time it took her to complete them.
To find the unit rate, we can divide the number of math questions completed by the time in minutes.
For example, for the first data point, the unit rate would be 12 questions / 36 minutes = 0.33 questions per minute.
The unit rate for each data point can be calculated in the same way.
So, the unit rate could be calculated as follows:
Unit rate = Number of math questions / Time in minutes
Unit rate = 12 questions / 36 minutes = 0.33 questions per minute
Unit rate = 16 questions / 48 minutes = 0.33 questions per minute
Unit rate = 20 questions / 60 minutes = 0.33 questions per minute
Unit rate = 24 questions / 72 minutes = 0.33 questions per minute
Unit rate = 28 questions / 84 minutes = 0.33 questions per minute
Therefore, the unit rate for each data point is 0.33 questions per minute.
in kid words
The unit rate tells us how many math questions Olivia completed in one minute. It is found by dividing the number of math questions by the time in minutes.
For example, if Olivia completed 12 math questions in 36 minutes, the unit rate would be 0.33 questions per minute.
We can calculate the unit rate for each data point in the table by dividing the number of math questions completed by the time in minutes.
No matter how many questions Olivia completed or how long it took her, the unit rate is always 0.33 questions per minute.
