Question

A novelist can write 2and 1 fourth pages in 3 fourths hour. How many pages can she write per hour?

Answer 1

The novelist can write 3 pages per hour

Explanation:

Unit rate is the work done per unit time.

Given

Number of pages = p =
`2(1)/(4) = (9)/(4)` pages

Time =t =
`(3)/(4)` hours

In order to find the number of pages per hour, we have to divide the number of pages by hours.

So,

`Pager\ per\ hour = ((9)/(4))/((3)/(4))\\Using\ ((a)/(b))/((c)/(d)) = (a)/(b) * (d)/(c)\\pages\ per\ hour = (9)/(4) * (4)/(3)\\= 3\ pager\ per\ hour`

Hence,

The novelist can write 3 pages per hour
