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

The Time taken by Carmen to read 140 pages of book is 261.14 min

Explanation:

Given as :

The time taken by Carmen to read 67 pages of book = 125 minutes

Let time taken by Carmen to read 140 pages of book = x minutes

Now,
`(Time taken)/(Work done)` = constant

∵ time taken by Carmen to read 67 pages of book = 125 minutes

So,time taken by Carmen to read 1 page of book =
`(125)/(67)` min

∴ time taken by Carmen to read 140 pages of book =
`(125)/(67)` × 140 min

Or, time taken by Carmen to read 140 pages of book = 1.8656 × 140 min = 261.14 minutes

Hence The Time taken by Carmen to read 140 pages of book is 261.14 minutes Answer
