Answer:
x=10
Step-by-step explanation:
Using Pythagorean theorem,
(√13^2-12^2)×2
(√169-144)×2
(√25)×2
5×2=10
5 1/2 pages in 12 minutes.
11/2 pages in 12 minutes
How many pages in an hour?
well, an hour has 60 minutes
Let's write a proportion
11/2 / 12 = x/60
cross multiply
(11/2 * 60) = 12x
330 = 12x
divide both sides by 12
27.5 or 27 1/2 = x
27.5 pages per hour.
Hope this helps
