To find out how many hours a tiger sleeps in 7 weeks, we first need to determine the total number of 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 in 49 days, there are: \[ 49 \text{ days} \times 24 \text{ hours/day} = 1176 \text{ hours} \]
-
Since a tiger sleeps between 18 to 20 hours each day, we can calculate the total sleep in hours for both extremes over 49 days:
-
For 18 hours of sleep per day: \[ 49 \text{ days} \times 18 \text{ hours/day} = 882 \text{ hours} \]
-
For 20 hours of sleep per day: \[ 49 \text{ days} \times 20 \text{ hours/day} = 980 \text{ hours} \]
-
So, the total number of hours a tiger sleeps in 7 weeks is between 882 and 980 hours.
The correct response is: 882 to 980 hours.
