To find out how many hours a tiger will sleep in 7 weeks, we first need to determine the total number of hours in 7 weeks and then calculate the sleep based on the provided sleep duration of 18 to 20 hours a day.
-
Calculate the total number of days in 7 weeks: \[ 7 \text{ weeks} \times 7 \text{ days/week} = 49 \text{ days} \]
-
Calculate the sleep hours for 18 hours per day: \[ 49 \text{ days} \times 18 \text{ hours/day} = 882 \text{ hours} \]
-
Calculate the sleep hours for 20 hours per day: \[ 49 \text{ days} \times 20 \text{ hours/day} = 980 \text{ hours} \]
Thus, in 7 weeks, a tiger will sleep between 882 to 980 hours.
