Question

Carmen reads 6/7 of a page in her library book in 12/5 minutes. At this rate, how many minutes does it take her to read the whole book if it has 140 pages?

Answer 1

392 minutes

Explanation:

She reads 6/7 of a page in 12/5 mins

She will read 1 page in (12/5)* (7/6) mins

She will read 140 pages in (12/5)*(7/6)*140 mins = 392 mins
