Worked solution

1. Convert pages to double-sided papers and divide by the photocopying rate to find the time.

On double-sided setting,
$600\text{ pages}=\frac{600}{2}=300\text{ double-sided papers}.$
Time taken
$=\frac{300}{30}=10\text{ minutes}.$

Answer

$10$ minutes

1. Convert 1 hour to minutes and use the photocopying rate to find the number of double-sided papers.

$1$ hour $= 60$ minutes

Number of double-sided papers photocopied
$= 30 \times 60 = 1800$

Answer

$1800$ double-sided papers
