Jorge’s printer can print 36 pages in 18 minutes. How many pages can it print in 1 hour
Sloan [31]

Answer:

120 pages can be printed in 1 hour.

Step-by-step explanation:

First divide 36 by 18 to figure out how many pages can be printed in a minute.

Like this: 36 pages ÷ 18 minutes = 2 pages in one minute.

Now, multiply 2 by 60 to figure out how many pages can be printed out in a hour.

Like this: 2 pages in one minute × 60 minutes ( one hour) = 120 pages in one hour can be printed.

Hope this helps!
