Answer: 8.7 years
Step-by-step explanation:
The average number of hours that a cat sleeps in a day is 16. The average cat lives 13 years.
We would determine the total number of hours that the average cat lives.
Assuming that there are 365 days in a year, it means that the number of days that an average cat lives would be
365 × 13 = 4745 days
There are 24 hours in a day, this means that the number of hour that a average cat lives would be
24 × 4745 = 113880 hours
If the cat sleeps
16 hours in 24 hours,
In 113880 hours, the cat would sleep
(16 × 113888)/16 = 75920 hours.
Converting 75920 hours to years, it becomes
75920/24 × 365 = 8.7 years
