Mr. Mandel gave his class 12 minutes to read. 5 1/2 pages in that time. At what rate, in pages per hour, did Claire read?

1 answer:

8 0

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

Answer 
=3,075.36 ml

Explanation
We must first convert pounds to kilograms. 1Lbs = 0.453592Kg.
So, 226 Lbs=226×0.453592
=102.512Kg
Now calculate how many ml Mr. Rogers would take.
30ml→1 Kg
What about 102.512 Kg?
102.512Kg→102.512×30
=3,075.36 ml
Since this figure is above the threshold ml per day, then we take the answer as 3,075.36 ml per day.
