How many pages can be read in 45 minutes? Answer with a decimal point rounded to the nearest tenth if necessary.

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.
