Hi Diana;
24,739,200 [(1 hour)/(60 minutes)]=412,320
412,320 [(1 day)/(24 hours)]=17,180
17,180 [(1 year)/(365 days)]=47
You are 47 years old.
You used minutes.

Nice!

So this takes some trial and error, unless you're very good about keeping track of how much and how often you're dividing the original number.

Here are the possibilities

365 days * 24 hours a day = 8760 hours in a year but 24,739,200/8760 = 2824.1095 years and that's too big to be the right answer

8760 hours * 60 minutes in an hour = 525, 600 minutes in a year, and 24,739,200/525,600 = 47.0685 years and that is quite possible

Therefore, the unit of time is minutes.
