Bryan needs to finish a book for

school. After 2 weeks, he has read

45 pages, and after 6 weeks, he has

read 135 pages. Find the rate of

pages per week that Bryan is

reading

22.5 pages per week

Step-by-step explanation:

Considering that After 2 weeks, he has read

45 pages, and after 6 weeks, he has

read 135 pages

Difference in weeks = 6-2=4 weeks

Difference in pages=135-45=90

Rate per week will be 90:4=22½ pages per week

To prove this

If 1 week is 22½

2 weeks will be 2*22½=45

6 weeks will be 6*22½=135

Therefore, the reading rate is 22.5 or 22½ pages per week
