Leo reads 10 pages in 1/2 hour. What is the unit rate for pages per hour? For hours per page?

Answers

10pages/.5hour
To figure out how many pages he can read in one hour, multiply the numerator and denominator by 2.
Leo can read twenty pages in one hour.
Hours per page is done like this
.5hour/10pages
To find out how many hours it takes to read one page, divide the top and bottom by ten.
It takes him .05 of an hour (3 minutes) to read one page.

Final answer:

The unit rate for Leo's reading is 20 pages per hour and 0.05 hours per page.

Explanation:

To find the unit rate for pages per hour, we need to adjust Leo's reading speed to reflect a full hour rather than half an hour. Since he reads 10 pages in half an hour, then in a full hour, which is twice as long, he would read twice as many pages. So, Leo's rate in terms of pages per hour is 20 pages per hour.

To find the unit rate for hours per page, we flip the ratio. So instead of looking at it as 'pages over hours,' we're looking at it 'hours over pages'. Leo reads 10 pages in half an hour, that is 1 page in 1/20 of an hour (or 0.05 hours). Therefore, his rate in terms of hours per page is 0.05 hours per page.
