Answer 2

Time taken by Miko to eat 9 cookies = 78 minutes
Given that she ate each cookie at equal intervals
Therefore
Time took by Miko to ate one cookie = 78/9 minutes
                                                               = 26/3
                                                               = 8 and 2/3 
                                                               = 8  2/3
