Miss graves gave her class 12 minutes to read carrie read 5 1/2 pages in a time what rate in pages per hour you carry read

12 minutes : 5 1/2 pages =        : 60 minutes (1 hour)

SCALE FACTOR: 60 minutes divided by 12 minutes = 5
Use your scale factor to figure out the missing info. So, in this case 5 multiplied by 5.5 pages to figure out how many pages she reads in 60 minutes (1 hour). We are multiplying it because we are going to 12 minutes to 60 minutes a greater amount of minutes. If we wanted to figure out how many pages she reads in 1 minute we would divide 12 by 5.

5.5 pages x 5 (Scale factor) = 27.5 pages

ANSWER: Carries reads 27/5 pages in 1 hour!
