Math Problem Statement
A printer in the school computer lab prints 56 pages in 4 minutes. At this rate how many pages does it print in 7 minutes?
Solution
To determine how many pages the printer can print in 7 minutes, we'll use the concept of unit rates.
-
Calculate the printing rate per minute:
-
Calculate the number of pages printed in 7 minutes:
Thus, the printer will print 98 pages in 7 minutes.

Here are some related questions for practice:
- How many pages would the printer print in 10 minutes?
- If the printer worked for 30 minutes at the same rate, how many pages would it print?
- How many minutes would it take to print 196 pages?
- If the printer's speed increased by 50%, how many pages would it print in 7 minutes?
- How many pages would be printed in half an hour?
Tip: When working with rates, always calculate the unit rate first (e.g., pages per minute) to make solving related problems easier.
