And here are the potential answers...
So... this question is just asking for a basic
proportion.
In all of these types of questions we just have to read carefully.
Okay, not that carefully. The Hazmat suit is a bit much.
In this problem, we have 3 hours swimming... 4 hours hiking... and 2 hours snorkeling
For a total of 9 hours.
So the question just wants to know... what proportion of Jenna's day is spent swimming?
Virtually, at least... Well, swimming is 3 hours.
Her total Wii sports time in a day is 9 hours... so the equation is 3 over 9...
...which reduces to 1 over 3...
...and the answer is A.
As in "Aerobic activity."
