- 100 pages are printed in 5 minutes.
To find:
- Time taken to print 50 pages.
Since the number of pages and time taken are directly proportional, we can set up a proportion to find the time taken to print 50 pages.
Proportion:
```
100 pages / 5 minutes = 50 pages / x minutes
```
Solving for x:
```
x minutes = (5 minutes * 50 pages) / 100 pages
x minutes = 2.5 minutes
```
Therefore, it takes 2.5 minutes to print 50 pages.
