how long will it take together to eat 36 cones
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

It is very simple arithmetic problem of the level for 4-th grade students.

First person's rate is 36/3 = 12 cones per hour. Her friend's rate is 36/2 = 18 cones per hour. Their combined rate is 12 + 18 = 30 cones per hour. The time for both to eat 36 cones is this ratio = hours = 6 times 12 minutes = 1 hour and 12 minutes. ANSWER
