Hey,
Here's the question:
A father distributes $96 to his 3 children according to the following instructions: the middle child gets $12 less than the oldest, and the youngest receives one third as much as the middle child. How much does each receive?
My problem is that my solution works (at least I think it does) but the textbook says otherwise.
I got:
OLDER CHILD: $37.20
MIDDLE CHILD: $25.20
YOUNGEST: $33.60
Textbook:
OLDEST: $48
MIDDLE CHILD: $36
YOUNGEST: $12
Now, I'm not an idiot right, I get that one third as much means, well, one third as much, right? But when I used that logic for a similar question I get the wrong answer. Here was the other question:
A biathlon event involves running and cycling. kim can cycle 30km/h faster than she can run. if kim spends 48 minutes running and a third as much time again cycling in and event that covers a total distance of 60 km, how fast can she run?
If you take her cycling as 16 minutes, which is a third of 48, you get the wrong answer. So I am confused by this double standard unless I'm missing some slight grammar rule or something.
