How many pages would same have finished in 126 minutes

Sedaia [141]

Answer:

Sam will finish 42 pages in 126 minutes.

Step-by-step explanation:

Number of pages read by Sam = 6

Time taken to read these pages = 18 minutes

Rate at which Sam is reading the pages of the book = $\frac{\text{Number of pages read}}{\text{Time taken to read these pages}}$

= $\frac{6}{18}$

= $\frac{1}{3}$ pages per minute

Number of pages read in 126 minutes = Rate of reading × Time

= $\frac{1}{3}\times 126$

= 42 pages

Therefore, Sam will finish 42 pages in 126 minutes.
