To find out how many newspapers the machine will print in 2 hours, we first need to determine the number of newspapers it prints per minute, and then multiply that by the number of minutes in 2 hours.
First, let's calculate the number of newspapers printed per minute:
1500 newspapers / 45 minutes = 33.33 newspapers per minute (rounded to two decimal places)
Next, we need to calculate the number of minutes in 2 hours:
Since there are 60 minutes in 1 hour, we have:
2 hours * 60 minutes = 120 minutes
Finally, we can calculate the number of newspapers printed in 2 hours:
33.33 newspapers per minute * 120 minutes = 3,999.6 newspapers
So, the machine will print approximately 3,999 newspapers in 2 hours.
(45min)(1hr/60min) = 0.75hr
1500/0.75hr = x/2hr
x = 4000 newspapers
