Answer:

27 minutes

Step-by-step explanation:

Hello!

500 and 900 are both multiples of 100, so let's first find the rate at which it takes Kofi to type 100 pages.

  • 15m = 500
  • 15m / 5 = 500/5
  • 3m = 100

It takes 3 minutes to type 100 papers.

Since 900 is 9 times 100, we can also multiply the time by 9.

  • 3m = 100
  • 3m*9 = 100*9
  • 27m = 900

It takes 27 minutes to type 900 papers.
