Please show work

Answer 1

12 hours x 60 minutes = 720 minutes.

720/360 = 2 minutes per page.

400 x 2 = 800 minutes or 13 hours and 20 minutes

Answer 2

Lauren will read 400 pages in 13.33 hours.

Explanation:

Lauren took 12 hours to read a 360 page book.

Or we can say that 360 pages were read in = 12 hours.

So, 400 pages will be read in =
`(12*400)/(360)`

= 13.33 hours.

Hence, Lauren will read 400 pages in 13.33 hours.
