Penny reads 12 pages in 1/4 of an hour. What is the unit rate of pages per hour, and what is the unit rate of hours per page? I know the unit rate of pages per hour is 48, but I am stuck on the unit rate of hours per page. I'm coming up with .020833. Please help. Thanks.

Answers

Your correct because 1/4 isn’t necessarily an hour it’s 15 minutes. So if yu divide that you would get .020833 yu would just have to round.

Penny can read 1 page in 1 minute and 14 seconds.

What is a unitary method?

A unitary method is a mathematical way of obtaining the value of a single unit and then deriving any no. of given units by multiplying it with the single unit.

Given, Penny reads 12 pages in 1/4 of an hour.

Now In (1/4)×4 hours, Penny can read (12×4) pages which is in 1 hour she can read 48 pages.

Now to obtain the unit rate of hours per page is we have to divide 1 hour by 48 pages which is (1/48) =  0.020833 hours or (0.020833×60) minutes = 1.24 minutes or 1 minute 14 seconds.

An inequality is a relation which makes a non-equal comparison between two numbers or mathematical expressions.

here, we have,

Given that

the number of pages he read each day is "p", the number of pages he will read from Monday to Friday is 5p (Monday to Friday is 5 days)

If he has read  50 pages of a novel, the total number of books he has read will be 50 + 5p
