Answer:
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
