1 hour = 60 minutes        Multiply both sides of this equation by 12

12 hours = 720 minutes

Now we can set up this equation:

$$\frac{1500 \, \text{ papers}}{45\,\text{ mins}}=\frac{x}{720\,\text{ mins}}$$          and solve for x by multiplying both sides by 720 mins.

$$720\,\text{ mins}\,*\,\frac{1500 \, \text{ papers}}{45\,\text{ mins}}=x \\~\\ 24,000\,\text{ papers}=x$$
