So. . Let's get started with formulas. . I KNOW you hate formulas!! So do I, but we have to use them. No "buts". . So, how many minutes are in 2 weeks? . Search it up. For your convenience, it is 20,160 minutes. . Well, I think you have your answer, since each quiz is 5 minutes, 5 times 50 (5 x 50) is 2,500 minutes. . Yes, you can do 50 quizzes and MUCH MUCH more in 2 weeks. . Hope I helped!!
