Working at a constant rate, a copy machine makes 20 copies of a one-pa...
To find the number of hours it takes to make 4,800 copies of a one-page document, we need to use the information given about the copy machine's constant rate.
Given:
- The copy machine makes 20 copies of a one-page document per minute.
- We want to find the number of hours it takes to make 4,800 copies.
Converting minutes to hours:
Since the rate given is in minutes, we need to convert the time to hours to match the units.
- 1 hour = 60 minutes
Therefore, we can say that the copy machine makes 20 copies per minute, which is equivalent to:
- 20 copies/minute * 60 minutes/hour = 1,200 copies/hour
Finding the number of hours needed:
Now that we know the copy machine makes 1,200 copies per hour, we can find the number of hours needed to make 4,800 copies.
- Number of hours = Total number of copies / Copies made per hour
- Number of hours = 4,800 copies / 1,200 copies/hour
- Number of hours = 4 hours
Therefore, it would take 4 hours to make 4,800 copies of a one-page document.
Conclusion:
The correct answer is option A) 4.

Finding the number of hours needed:
Now that we know the copy machine makes 1,200 copies per hour, we can find the number of hours needed to make 4,800 copies.
- Number of hours = Total number of copies / Copies made per hour
- Number of hours = 4,800 copies / 1,200 copies/hour
- Number of hours = 4 hours
Therefore, it would take 4 hours to make 4,800 copies of a one-page document.
Conclusion:
The correct answer is option A) 4.

The copy machine produces 20 copies of the one-page document each minute. Because there are 60 minutes in an hour, the constant rate of 20 copies per minute is equal to 60 x 20 = 1,200 copies per hour. With the machine working at this rate, the amount of time that it takes to produce 4,800 copies of the document is
4800 copies / 1200 copies/hours = 4 hours
