Julien spent 5 hours and 44 minutes mowing the lawn and 3 hours and 24 minutes trimming the hedge and some shrubs. How long did he work altogether?

Add the minutes:
44 + 24 = 68

Step 1: 68 minutes is 1 hour and 8 minutes.

So we take the 1 hour and add it to the 5 hours of mowing the lawn and 3 hours of trimming the hedge and we get:
5 + 3 + 1 = 9 hours

We take the 8 minutes of Step 1 and we have:
9 hours and 8 minutes
