To find out how many hours the skater will practice in 9 weeks, you can use the following calculation:
- Determine the total number of hours practiced per day: 9 hours
- Calculate the total number of days in 9 weeks: 9 weeks * 7 days/week = 63 days
- Multiply the daily practice hours by the total number of days: 9 hours/day * 63 days = 567 hours
So, the skater will practice for 567 hours in 9 weeks.
