work and rates problem

[jalshri]

Jack is putting together gift boxes at a rate of 3 per hour in the first hour. Then Jill comes over and yells,"work faster!" Jack, now nervous ,works at the rate of only 2 gift boxes per hour for the next 2 hours.Then Alex comes to Jack and whispers,"The steadiest hand is capable of the divine." Jack,calmer,then puts together 5 gift boxes in the fourth hour. What is the average rate at which Jack puts together gift boxes over the entire period?
Ans: 3 boxes per hour
