Question

Mr. Ramirez gave his class

Answer 1

Answer:

38 pages per hour

Step-by-step explanation:

Rate of reading = $\frac{\text{Total number of pages read by Davida}}{\text{Time taken to read}}$

By substituting the given values in the question,

Total number of pages read by Davida = $28\frac{1}{2}$ = $\frac{57}{2}$

Time taken by Davida = 45 minutes

Since, 1 minute = $\frac{1}{60}$ hours

Therefore, 45 minutes = $\frac{45}{60}=\frac{3}{4}$ hours

Rate of reading = $\frac{\frac{57}{2}}{\frac{3}{4} }$

                          = $\frac{57}{2}\times \frac{4}{3}$

                          = 38 pages per hour

Therefore, rate of reading by Davida is 38 pages per hour.
