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!
