Step-by-step explanation:
just think ab it and you can figure it out using real worl problems
We have been given that an antique car is a car that is 25 years old or older. We are asked to find the hours it will take a car to become an antique.
We know that 1 year equal to 365 days.
1 day is equal to 24 hours.
To find number of hours in 1 year we will multiply 365 by 24.


Now we will multiply hours in one year by 25 to find hours in 25 years.



Therefore, it will take
hours for a car to become an antique.
