Suzanne can read 1 page in 3 minutes. how many pages can she read in 5 hours?
pychu [463]
If Suzanne can read 1 page in 3 minutes, that means that in ONE hour, she can read 20 pages.
1 page per 3 minute
60minutes : 3 = 20 pages
Now, multiply 20 pages by 5 hours.
20 x 5 = 100.

I hope it helps! (She's pretty slow at reading)
