Answer:
Sessions needed= 12
Step-by-step explanation:
Giving the following information:
Total hours= 12 hours
Practice= 3/4= 0.75 of an hour
Already practiced= 3 hours
First, we need to determine how many minutes does she practice each session:
Minutes per session= 0.75*60= 45 minutes
Now, we divide the total practice in minutes required for the minutes per session:
Sessions needed= (9*60) / 45
Sessions needed= 12
