Hi there!
In order to find your answer, you'll need to use the cross produc method :
23 pages → 60 seconds
1 page → x seconds
(60 × 1) ÷ 23 = x seconds
60 ÷ 23 = x seconds
2.61 ≅ x seconds
You answer is : It takes a printer about 2.61 seconds to print one page.
There you go! I really hope this helped, if there's anything just let me know! :)
