Transcript

00:03

This question has been run through the Shmoop-a-tron 5000...

00:06

Jenna spends 3 hours a day swimming, 4 hours a day hiking, and 2 hours a day snorkeling.

00:11

Okay, so it's all on the Wii, but still...

00:14

at least her thumbs are getting a really great workout.

00:17

What proportion of her time does she spend Wii-swimming?

00:21

And here are the potential answers...

00:24

So... this question is just asking for a basic

00:25

proportion.

00:26

In all of these types of questions we just have to read carefully.

00:30

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.

01:01

As in "Aerobic activity."
