Answer:

B.

Step-by-step explanation:

12 copies = 1 minute

In 5 mins = 60

In 10 mins = 120

In 15 mins = 180

In 20 mins = 240

Operation used: Multiplication

[tex]12 \times 5 = 60[/tex]

[tex]12 \times 10 = 120[/tex]

[tex]12 \times 15 = 180[/tex]

[tex]12 \times 20 = 240[/tex]

12 12 12 12

× 5 × 10 × 15 × 20

------- -------- ------- --------

60 120 60 240

+ 12

---------

180

Hope this helps
