Question

Tiffany types 11/20 of a page in 3/4 of an hour. At this rate, how many pages will she type in 3 hours? Express your answer as a decimal. (PLEASE HELP)

Answer 1

Explanation:

3/4 of an hour = 45 minutes

Part completed in 45 minutes = 11/20 of a page

Part completed in 1 minute =
`(11)/(20)` ÷ 45

`=(11)/(20)*(1)/(45)=(11)/(900)`

Part completed in 60 minutes or 1 hour =
`(11)/(900)*60=(11)/(15)`

Pages completed in 3 hours =
`(11)/(15)*3=(11)/(5)=2(1)/(5)`

= 2.2 pages
