Pam read 126 pages of her summer reading book in 3 hours. Zack read 180 pages of his summer reading book in 4 hours. If they continue to read at the same speeds, will they both finish the 215 page book after 5 total hours of reading?

Zack reads faster so he will finish first
Pam= 126/3 = 42/1
Zack= 180/4 =45/1
Now multiply the unit rates by 5 each
Pam= 210/5
Zack= 225/5
