One math student, John, can solve these 6 math problems in 20 minutes while another student, Juaquine, can solve them at a rate of I problem per 4 minutes. Who works faster?
John: 6 problems in 20 minutes = 6/20 = 0.3 problem per minute
Juaquine: 1 problem in 4 minutes = 1/4 = 0.25 problem per minute
It looks like John wins the trophy.
