To calculate the number of hours a tiger will sleep in 7 weeks, we need to multiply the number of hours it sleeps per day by the number of days in 7 weeks.
Since a tiger sleeps 18 to 20 hours a day, we can calculate the range by multiplying these values by 7:
18 hours x 7 days = 126 hours
20 hours x 7 days = 140 hours
So, a tiger will sleep between 126 to 140 hours in 7 weeks. Therefore, the correct answer is "126 to 140 hours".
A tiger sleeps 18 to 20 hours a day. How many hours will a tiger sleep in 7 weeks? 630 to 700 hours. 126 to 140 hours. 882 to 980 hours. 2.5 to 2.9 hours.
