Answer 1

To calculate how many hours a tiger will sleep in 7 weeks, we first need to determine the total number of hours in 7 weeks.

1. Calculate the total hours in 7 weeks:

   • There are 7 days in a week, so in 7 weeks there are: \[ 7 \text{ weeks} \times 7 \text{ days/week} = 49 \text{ days} \]
   • Each day has 24 hours, so: \[ 49 \text{ days} \times 24 \text{ hours/day} = 1176 \text{ hours} \]

2. Now, calculate the total sleep hours:

   • A tiger sleeps between 18 to 20 hours a day. Therefore, over 49 days:
     • Minimum sleep: \[ 49 \text{ days} \times 18 \text{ hours/day} = 882 \text{ hours} \]
     • Maximum sleep: \[ 49 \text{ days} \times 20 \text{ hours/day} = 980 \text{ hours} \]

3. Combine both results:

   • So, in 7 weeks, a tiger will sleep between 882 to 980 hours.

The correct answer is 882 to 980 hours.
