Answer:
157.5 pages
Step-by-step explanation:
First, find your rate. You want to know how many pages you can read per minute. We can use any nuber, but using 2 minutes will be the simplest solution:
2m = 7
--- --- <---- Here we divide both sides of the equal sign by 2
2 2
m = 3.5 <---- we read 3.5 pages per minute
45 x 3.5 = 157.5 (We multiplied 45 because it's the number of minutes we have, by the 3.5 pages we read each minute. This gives us our total of 157.5 pages in 45 minutes.
