Question

5) Tim loves reading fiction, and he can read 100 pages in 2 hours. How many pages he can read in 48 minutes?

Answer 1

`40\ pages`

Explanation:

Remember that

1 hour=60 minutes

so

2 hours=120 minutes

Using proportion

`(100)/(120)(pages)/(minutes)=(x)/(48)(pages)/(minutes)\\ \\x=100*48/120\\ \\x=40\ pages`

Answer 2

40 pages

Explanation:

Lets change hours to minutes

1 hours = 60 minutes

2 hours = 120 minutes

We will use ratios to solve

100 pages x pages

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

120 minutes 48 minutes

Using cross products

100 * 48 = 120 * x

Divide each side by 120

100 *48/120 = 120x/120

40 =x

Tim can read 40 pages
