Question

Jayson reads the first 48 pages of a 480-page book in 3 days.
Marcus reads the first 50 pages of a 400-page book in 4 days.
Nina reads the first 120 pages of a 600-page book in 5 days.
It will take Jayson ? days to finish his book.
It will take Marcus ? days to finish his book.
It will take Nina ? days to finish her book.

Answer 1

Jayson reads = 48 pages out of 480 pages

Jayson reads 48 pages = 3 days

Jayson reads in 1 day = 48/3 = 16 pages

Jayson finishes reading 480 pages = 480 / 16

= 30 days

Marcus reads = 50 pages out of 400 pages

Marcus reads 50 pages = 4 days

Marcus reads in 1 day = 50/4 = 12.5 pages

Marcus finishes reading 400 pages = 400 /12.5

= 32 days

Nina reads = 120 pages out of 600

Nina reads 120 pages = 5 days

Nina reads in 1 day = 120/5 = 24 pages

Nina finishes reading 600 pages = 600/24

= 25 days
