In order to do this question, we must first convert our units to ensure they are all the same. As the question requests us to answer in hours, that would be the most productive unit to convert to. 30 minutes is equal to 0.5 hours, and 15 minutes is equal to 0.25 hours. Now, we simply add them all together. 0.5 hours + 0.25 hours + 1.5 hours + 0.75 hours = 3 hours total of planned activities.
