If you remember, at the end of Maths at: the Movies, 21, we asked you how old is Ben on his next Birthday, if he is currently 50 years, 50 Months, 50 Weeks, 50 Days, and 50 Hours old?
The best way to answer this question is to start with the hours and convert them to days,
i.e. 50 hours = 2 days 2 hours.
Then convert the 52 days into weeks,
52 days = 7 weeks 3 days,
and so on.
Following this process you should discover that Ben is currently 55 years old and, thus, will be 56 on his next birthday.
|Doesn't Ben look good for his age?|
Of course the easiest way is to get a computer to do it. Wolfram alpha may not be good for much, but unit conversions are where it excels.
