To find how many pages jack reads per minute, divide 60 by 20.
60 ÷ 20 = 3
Jack read 3 pages per minute.
Now, find how many pages he will read in 75 minutes by multiplying 3 by 75.
3 × 75 = 225
--
The proportional equation is the number of pages read per minute (3) times the time spent reading (r) equals total pages read (t).
t = 3r
Hope this helps :)
