Answer:
Printer B
Step-by-step explanation:
If printer A prints 36 pages every 1.5 minutes (90 seconds) we can divide 90 seconds by 36 to determine how long it takes Printer A to print one page. When we do that, we get 2.5 seconds which means it takes Printer A 2.5 seconds to print one page.
If we do the same with Printer B, we can divide 3 minutes (180 seconds) by 114 to get about 1.5 seconds which means it takes Printer B about 1.5 seconds to print one page.
If we do the same with Printer C, we can divide 5 minutes (300 seconds) by 115 to get about 2.6 seconds which means it takes Printer C about 2.6 seconds to print one page.
From this we can determine which printer prints the fastest and our answer will be Printer B.
