Answer:

3 minutes

Step-by-step explanation:

To calculate this, you have to multiply 4.5 minutes by 8. This will give you the amount of pages that Wafa will print.

4.5 x 8 = 36 pages

Now that you have the amount of pages, you should divide it by the speed of the Sure-Fire printer. 12 ppm means that 12 pages can be printed in 1 minute.

36/12 = 3

Therefore, it would take 3 minutes if Wafa were to use her brother's Sure-Fire printer.

Answer:

3 minutes

Step-by-step explanation:

Apricot prints 8 pages per minute, the Sure-fire prints 12.

That means Wafa's brother's printer is 1.5 times faster than Wafa's own.

That means his printer can print the document in 4.5min / 1.5 = 3min
