To calculate how many hours a tiger sleeps in 7 weeks, we first need to find the total number of hours in 7 weeks and then calculate the sleep range.
1 week has 7 days, so 7 weeks has: \[ 7 \text{ weeks} \times 7 \text{ days/week} = 49 \text{ days} \]
Next, calculate the number of hours in 49 days: \[ 49 \text{ days} \times 24 \text{ hours/day} = 1176 \text{ hours} \]
Now, we can determine how many hours a tiger sleeps in that time frame. A tiger sleeps between 18 to 20 hours a day. Therefore, we calculate the minimum and maximum sleep for 49 days as follows:
Minimum Sleep: \[ 49 \text{ days} \times 18 \text{ hours/day} = 882 \text{ hours} \]
Maximum Sleep: \[ 49 \text{ days} \times 20 \text{ hours/day} = 980 \text{ hours} \]
So, a tiger will sleep between 882 to 980 hours in 7 weeks.
The correct answer is: 882 to 980 hrs.
