<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>
