Answer:
Zac will finish, Pam won’t
Step-by-step explanation:
Let’s have the individual reading speeds
The individual reading speeds are the number of pages divided by hours taken
For Pam; 126/3 = 42 pages per hour
For Zac; 180/4 = 45 pages per hour
In five hours, Zac would read; 45 * 5 = 225 pages
In five hours, Pam would read 42 * 5 = 210 pages
The unit rate would probably be 21 per 3.5
