Question

Richard can read of a book in of an hour. At this rate, how much can Richard read in one hour?
A.
of a book

B.
of a book

C.
books

D.
of a book

Answer 1

To determine how much Richard can read in one hour, we need to know how much of the book he can read in half an hour. Let's define it like this:

Let \( R \) be the fraction of the book Richard can read in half an hour. Then, if he reads \( R \) in half an hour, in one hour (which is double half an hour), he can read:

\[
2R
\]

You didn't specify the actual fraction he can read in half an hour (the original problem likely omitted some values). Let’s assume Richard can read \( \frac{1}{4} \) of a book in half an hour (for example).

Using this assumption, we calculate:

\[
R = \frac{1}{4} \quad \text{(in half an hour)}
\]

Thus, in one hour:

\[
2R = 2 \times \frac{1}{4} = \frac{2}{4} = \frac{1}{2}
\]

If \( R \) is any other fraction \( x \), then:

\[
\text{Amount read in one hour} = 2x
\]

Please provide the specific fraction for the reader in half an hour so I can give you the exact answer out of the given options (A, B, C, D).
