9 years to hours is 78888 hours
Solution:
Given that we need to convert 9 years to hours
We convert 9 years into hours by converting years to days, days to hours.
Let us see the calculation. So, take the term 9 years.
[tex]9 year = 9 \times 1year[/tex]
1 year has 365 days. But when we observe carefully, a span of 9 years has 2 leap years
Leap year: A year, occurring once every four years, that has 366 days
Now considering two leap years in a span of 9 years , we get,
[tex]\rightarrow 9 \times 1 \text { year }=9 \times 365 \text { days }=3285 \text { days }[/tex]
we can add extra day in a leap years in next step
3285 + 2 days = 3287 days
We know that one day has 24 hours.
[tex]3287 \times 1 \text { day }=3287 \times 24 \text { hours } = 78888 hours[/tex]
Hence 9 years in hours is 78888 hours
