proportion.

Okay, not that carefully. The Hazmat suit is a bit much.
- 00:34
In this problem, we have 3 hours swimming... 4 hours hiking... and 2 hours snorkeling
- 00:39
For a total of 9 hours.
- 00:41
So the question just wants to know... what proportion of Jenna's day is spent swimming?
- 00:46
Virtually, at least... Well, swimming is 3 hours.
- 00:50
Her total Wii sports time in a day is 9 hours... so the equation is 3 over 9...
- 00:56
...which reduces to 1 over 3...
- 00:58
...and the answer is A.
