Answer:

13 minutes

Explanation:

Okay so you take 100 divided by 4 which would be 25

so that means she finishes 25 questions per minute

so, then you take every hundred (there's 3) and you divide that by 4

then you'd get 4 times 3 which would be 12 and then you add an extra minute with the remaining 25

the answer would be 13 minutes!

Answer:

  • 13 minutes

Explanation:

Solve by ratios:

  • x / 4 = 325 / 100
  • x / 4 = 3.25
  • x = 4*3.25
  • x = 13
