Lydia wrote 4.5 pages of her science report in one hour. What was her writing rate in
pages per minute?
A.
0.0075 PPM
B.
7.5 PPM
C.
0.75 PPM
D.
0.075 PPM
To find Lydia's writing rate in pages per minute, we need to divide the number of pages she wrote by the time it took her in minutes.
If Lydia wrote 4.5 pages in 1 hour, which is equivalent to 60 minutes, her writing rate is 4.5 pages / 60 minutes = 0.075 PPM.
Therefore, the correct answer is D. 0.075 PPM.
To find Lydia's writing rate in pages per minute, we need to divide the number of pages she wrote in one hour by the number of minutes in an hour.
There are 60 minutes in an hour, so we divide 4.5 pages by 60 minutes:
4.5 pages / 60 minutes = 0.075 pages per minute
Therefore, the correct answer is D. 0.075 PPM.
To find Lydia's writing rate in pages per minute, we need to determine how many pages she wrote in one minute.
We know that Lydia wrote 4.5 pages in one hour. To convert this to minutes, we need to multiply by 60 (since there are 60 minutes in an hour).
4.5 pages * 60 minutes = 270 pages.
Therefore, Lydia wrote 270 pages in 60 minutes.
Now, to find her writing rate in pages per minute, we divide the number of pages by the number of minutes:
270 pages / 60 minutes = 4.5 pages per minute.
So, Lydia's writing rate is 4.5 pages per minute.
Therefore, the answer is:
B. 7.5 PPM
