Here's a question that's part of a balanced, shmoopy breakfast...

00:07

The following scale drawing of a sailboat is in a ratio of 1 inch to 6 feet. 

00:12

Good thing, too, because we don't know many ants that like going out on the water.

00:16

What is the length of the actual sailboat in feet?

00:20

Here are the potential answers...

00:24

Ok hallelujah -- this question is about conversion.

00:29

Er, um, from inches to feet, that is. There are 12 inches in a foot and the problem

00:33

gives us that 1 inch on this scale model is 6 feet so...

00:38

...since the answers are all in feet, we only care about feet. Like Nike.

00:42

So to convert the drawing's 3.75 inches into real life feet,

00:46

we multiply the inches figure by 6 feet.

00:50

And we get 3.75 times 6 which is 22.5

00:55

The answer is 22 and a half feet.

00:57

Answer D.
