Answer:
38 pages per hour
Step-by-step explanation:
Rate of reading = [tex]\frac{\text{Total number of pages read by Davida}}{\text{Time taken to read}}[/tex]
By substituting the given values in the question,
Total number of pages read by Davida = [tex]28\frac{1}{2}[/tex] = [tex]\frac{57}{2}[/tex]
Time taken by Davida = 45 minutes
Since, 1 minute = [tex]\frac{1}{60}[/tex] hours
Therefore, 45 minutes = [tex]\frac{45}{60}=\frac{3}{4}[/tex] hours
Rate of reading = [tex]\frac{\frac{57}{2}}{\frac{3}{4} }[/tex]
= [tex]\frac{57}{2}\times \frac{4}{3}[/tex]
= 38 pages per hour
Therefore, rate of reading by Davida is 38 pages per hour.
