Question

Gwendolyn has already read 130 pages of her 400-page summer reading book. If she reads at an average rate of 45 pages per hour, how long will she need to finish the book? Write an equation to find the answer.

Answer 1

Total time=130/45+270/45
t=8.8hr
If she finishes the book with same speed
Then first 130 pages in speed of 45 pages /hrs .
So t=2.8hr
Rest are 270 pages with same speed

Answer 2

h=270/45

To find how many hours it takes to read the rest of the book, you have to divided the remainder of pages (270) by how many pages are read in a hour (45)
