of a page in 1 hour. At this
-

Answer 1

For this case we propose a rule of three:

$\frac {3} {5}$ page ---------->$\frac {3} {10}$ hour

x ---------------------------------> 1 hour

Where the variable x is the number of pages written in one hour.

$x = \frac {1 * \frac {3} {5}} {\frac {3} {10}}\\x = \frac {\frac {3} {5}} {\frac {3} {10}}\\x = \frac {10 * 3} {5 * 3}\\x = \frac {30} {15}\\x = 2$

Thus, Ophelia types 2 pages in 1 hour.

Answer:

Ophelia types 2 pages in 1 hour.
