Question

Gwen 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?

Answer 1

It should take Gwen 6 hours for her to finish her book.

Answer 2

Gwen has already read 130 pages of 400 pages. Then she has to read

400-130=270 pages.

If she reads at an average rate of 45 pages per hour, then it will take her

`270:45=6`

hours to end reading.

Answer: 6 hours.
