Math Help - Playing with time and units

I was trying to resolve this math quiz:


A centimeter is one hundredth of a metre. So a ‘centifortnight’ would be one hundredth of a fortnight.

The length of a ‘centifortnight’ would be closest to how many hours.


I did my calculations and got this:
There are 24 hours in one day, 7 days in one week. Therefore, 2 weeks is equal to 2 x 7 x 24 = 336 hours/ 100 = 3.36 hours.


But I saw the following this( 12,096 seconds = 1 centifortnight. 2.4 hours )on a website and I think 2.4 hours is wrong but the 12,096 seconds is right.Anyone agrees with me?

. They calculated the number of seconds correctly but then didn't convert it properly.

I'm a bit concerned about 3.36 hours figure. The question implies that you should round your answer to the nearest integer
