Paul reads a 40 page book in 30 minutes.
(a) What is Paul's reading rate of pages per miunute?
(b) If he continues to read at the same rate, how many pages will he read in 3.5 hours?

he reads (40 pages)per (30 minutes) or
40/30 pages/min
= 4/3 pages/min.
How many minutes are there in 3.5 hours ?
Multiply that number by 4/3
