Answer: 61320 hours
Explanation:
This may be a little tricky because it involves a lot of conversions.
The conversions we need to know are:
24 hours=1 day
365 days=1 year
Note: I am disregarding the leap year because it was not mentioned in the question.
Now, we can solve the problem with the given proportions.
With the units cancelling out, we get 61320 hours.
