Final answer:
Wilbur spends 45 minutes practicing the piano each day, which amounts to a total of 10.5 hours over the span of 2 weeks.
Step-by-step explanation:
The student is asking how much time Wilbur will spend practicing the piano over a span of 2 weeks. To calculate this, we need to consider that there are 7 days in a week, so 2 weeks have 14 days. Wilbur practices for 45 minutes a day. Therefore, we multiply the number of days he will practice in two weeks by the daily practice time.
Calculation: 45 minutes/day x 14 days = 630 minutes.
However, to express the time in hours, we divide the total minutes by 60 (since there are 60 minutes in an hour).
Conversion to hours: 630 minutes ÷ 60 minutes/hour = 10.5 hours.
So, Wilbur spends a total of 10.5 hours practicing piano over the course of 2 weeks.
