Answer:
Marie would finish playing volleyball at 9:15am.
Step-by-step explanation:
If Marie went on a 2 hour and 15 minute hike at 5:15am on Wednesday, then she would finish hiking at 7:30am.
Then, after playing volleyball for an hour and 45 minutes, she would finish playing volleyball at 9:15am.
Here is the work in simpler terms:
5hr 15min + 2hr 15min =
7hr 30min or 7:30am
7hr 30min + 1hr 45min =
8hr + 75min =
9hr 15min or 9:15am.
