If 2 students can answer 40 questions in 1 hour, 1 student can answer 20 questions in 1 hour.

anonymous · Answer

its talking about 5 students tho

bahrom7893 · Answer

There are 60 minutes in one hour, 15 minutes is a quarter of 60 minutes, so in 15 minutes, 1 student can answer 20*(1/4) = 5 questions.
So if 1 student answers 5 questions in 15 minutes
5 students answer 5*5 = 25 questions in 15 minutes
