Question

Karen reads 20 pages of her book in half hour. If she reads for 3 hours at that same rate, about how many pages of her book can Karen read?

Answer 1

120 pagesStep-by-step explanation:

well we just need to multiply 180/30 because 60 by 3 and we are gonna be reading for 3 hours. so that is 6. then we multiply 20 by 6 which is 120

so she can read 120 pages

Answer 2

She can read 120 pages

Explanation:

We can use ratios to solve

20 pages x pages

--------------- = -----------

1/2 hour 3 hours

Using cross products

20 *3 = 1/2 x

Multiply by 2

20*3*2 = 1/2 *2 *x

120 = x

She can read 120 pages
