  # SAT I math problem

<p>This is the diagram:</p>

<p>Erin's locker
:
: ( 4 steps)<br>
:
:----------(16 steps)-------
:
:
(8steps)
:
Erin's classroom.</p>

<p>How many less steps would it be if she could go in a straight line?</p>

<p>edit: the forums won't allow the diagram to work, but if you imagine the "8 step" line to be hiked over to the far right of the "16 step" line, you have what it would look like. I hope that explanation works.</p>

<p>If I sketched your diagram correctly, I'd say she would save eight feet.</p>

<p>Was she walking 4 feet down, 16 feet to the right, and then eight feet down?</p>

<p>If so, then she walked a total of 12 feet down (imagine a line being drawn downward), and 16 feet to the right (that line now shifts to the right). Here you have two sides to a right triangle. The hypotenuse would be the straight line. </p>

<p>Initial path = 4 + 8 + 16</p>

<p>Hypotenuse path = 20 (3-4-5 triangle)</p>

<p>28-20 = 8 feet saved</p>

<p>god sometimes I don't know what I'm thinking when I can't figure out these problems. Thanks alot though, I always appreciate the help.</p>
