A scanning unit scans 270 pages in 3/4 hour. How many pages will be scanned in 2.5 hours ?
900
The scanning rate is found by dividing the number of pages by the time taken.
\(\text{Rate} = \frac{270}{3/4} = 270 \times \frac{4}{3} = 360\) pages per hour.
For 2.5 hours, the pages scanned are \(360 \times 2.5 = 900\)
Hence, 900 pages will be scanned in 2.5 hours.
