Answer :
It will take the teacher 1.25 hours to print 6,000 pages.
To calculate how long it will take to print 6,000 pages with a copy machine that can print 80 sheets per minute, we need to divide the total number of pages by the rate of printing per minute to find out the time in minutes, and then convert that time into hours if necessary.
Step 1: Divide the total number of pages by the printing speed to find the time in minutes.
Total pages: 6,000
Printing speed: 80 pages/minute
Time calculation: 6,000 pages divided by 80 pages/minute = 75 minutes
Step 2: Convert minutes into hours by dividing by 60 since there are 60 minutes in an hour.
Conversion to hours: 75 minutes divided by 60 minutes/hour = 1.25 hours
Therefore, it will take the teacher 1.25 hours to print 6,000 pages.
