Chapter 3.3, Problem 9P

On a space shuttle mission, a certain experiment is started 2 days, 14 hours, and 30 minutes into the mission. The experiment takes 1 day, 21 hours, and 47 minutes to run. When will the experiment be completed? Give your answer in days, hours, and minutes into the mission. Work with a sort of expanded form. In other words, work with

   $\text{2(days) + 14(hours) + 30(minutes)}$

and

   $\text{1(day) + 21(hours) + 47(minutes)}$

and regroup among days, hours, and minutes to solve this problem.
