Answer:

Step-by-step explanation:

3/4 of an hour = 45 minutes

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

Part completed in  1 minute = [tex]\dfrac{11}{20}[/tex] ÷ 45

                                              [tex]=\dfrac{11}{20}*\dfrac{1}{45}=\dfrac{11}{900}[/tex]

Part completed in 60 minutes or 1 hour = [tex]\dfrac{11}{900}*60=\dfrac{11}{15}[/tex]

Pages completed in 3 hours = [tex]\dfrac{11}{15}*3=\dfrac{11}{5}=2\dfrac{1}{5}[/tex]

                                                = 2.2 pages
