Question

Ms. Graves gave her class 12 minutes to read. Carrie read 5 1/2 pages in that time. at what rate, in pages per hour, did Carrie read?

Answer 1

We have:


`\sf(5.5)/(12)`

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


`\sf60/12=5`

Multiply both the numerator and denominator by 5.


`\sf5*5.5=27.5`


`\sf12*5=60`

So we have:


`\sf(27.5)/(60)`

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