Question

If Joan read 75 pages in 4 hours how long will it take her to read 250 pages?

Answer 1

This question belongs to unitary method .

Now the number of hours in which Joan reads 75 pages in = 4 hours.

So,,

Joan will read 1 page in =
`(4)/(75)` hours

And Joan will read 250 pages in=
`250 * (4)/(75) = 13.33` hours.

Hence Joan will read 250 pages in 13.33 hours.
