To find out how many hours a tiger sleeps in 7 weeks, we can first determine the total number of hours in 7 weeks:
1 week = 7 days
7 weeks = 7 * 7 = 49 days
1 day = 24 hours
49 days = 49 * 24 = 1,176 hours
Given that a tiger sleeps between 18 to 20 hours a day:
-
Minimum sleep in 7 weeks: \( 18 \text{ hours/day} \times 49 \text{ days} = 882 \text{ hours} \)
-
Maximum sleep in 7 weeks: \( 20 \text{ hours/day} \times 49 \text{ days} = 980 \text{ hours} \)
So, a tiger will sleep between 882 to 980 hours in 7 weeks.
The correct response is: 882 to 980 hours.
