To find the number of hours a tiger will sleep in 7 weeks, we need to multiply the number of hours a tiger sleeps in a day (18 to 20 hours) by the number of days in 7 weeks.
Number of hours in a day = 18 to 20 hours
Number of days in 7 weeks = 7 x 7 = 49 days
Therefore, the number of hours a tiger will sleep in 7 weeks is 18 x 49 to 20 x 49 hours.
Calculating the range:
18 x 49 = 882 hours
20 x 49 = 980 hours
So the tiger will sleep for 882 to 980 hours in 7 weeks.
Therefore, the correct answer is option D. 882 to 980 hours.
