At a math competition 2 students can answer 40 questions in 1 hour. at the same rate, how many questions could 5 students answer in 15 mins?

25 questions

Step-by-step explanation:

At a math competition 2 students can answer 40 questions in 1 hour.

Therefore, 1 student can answer in 1 hour =  

                                                                     = 20 questions

5 students can answer in 1 hour = 20 × 5 = 100 questions

60 minutes = 1 hour

15 minutes =   = 0.25 hours

5 students can answer in 0.25 hours = 100 × 0.25

                                                              = 25 questions

5 students could answer 25 questions in 15 minutes.
