Answer :
Answer: 61320 hours
Step-by-step 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.
[tex]7\text{years}*\frac{365 \text{days}}{1 \text{year}} *\frac{24\text{hours}}{1 \text{day}}[/tex]
With the units cancelling out, we get 61320 hours.
