Ms graves gave her class 12 min to read. carrie reads 5 1/2 pages in that time. at what rate, in pages per hour, did carrie read? plz write a proportion i will give you 100 pints

Hi there

To answer you question the answer is:

Carrie read at a rate of 27.5 pages per hour.

12 minutes is 1/5 of an hour so she read 5.5/(1/5)=5.5*5=27.5 pages per hour

27.5 pages per hour

Step-by-step explanation:

Well, first you make the 12 minutes into an hour (times by 5), then times the pages she read (5.5) by 5, which is 27.5, so she reads 27.5 pages per hour, you can also use 27 and a half pages per hour.

25.7 minutes per hour

Step-by-step explanation:

60÷12=5

27 1/2 pages/hour (Answer C)

Step-by-step explanation:

Find the unit rate:

5  1/2 pages       11/2 pages

=

 (12/60) hr           1/5 hour

To perform this division by 1/5 hour, invert and multiply:

5  1/2 pages       11/2 pages        11 pages      5

= = * = 27 1/2 pages/hour

 (12/60) hr           1/5 hour             2                1 hour

27 1/2

Step-by-step explanation:

Carrie read 5.5 pages in the span of 12 min., but the answer is requesting pages per hour, so we have to divide an hour in min. by the span of min that Carrie read.

1 hr = 60 min

60min / 12min = 5

That 5 we then multiply by 5.5, because if she read 5.5 pages in 12 min, she would keep that rate throughout the whole hour.

5.5 * 5 = 27.5 pgs

We can verify this by dividing the fractions of pages over time.

5.5 pg / 12 min = 0.458

27.5 pg / 60 min = 0.458

Hope I helped!!

66 pages per 1 hour

Step-by-step explanation:

Carrie read 27.5 pages per hour

To make this easier, you want to do 5 1/2 into a decimal. 5.5, next divide to find her pace per minute. 12/ 5.5 =2.1818
Multiply that by 60, and your answer is 130

We have:



Convert to a denominator of 60, since there are 60 minutes in an hour.



Multiply both the numerator and denominator by 5.





So we have:



Therefore Carrie read at a rate of 27.5 pages per hour.
