\section *{Introduction}


I saw an insect walking along the hallway in Building 76 this morning.  "How fast is it moving?" I wondered.  In this experiment, the speed of the insect will be determined using simple instruments.


\section {Observations}

I marked the hallway with peices of tape, using a ruler to place each piece 5 cm from the previous one.  Each time the insects forelegs reached a piece of tape, I noted the time with a hand operated stopwatch.

\begin {tabular} {r|r}
	0 & 0.0
	5 & 3.1
	10 & 5.9
	15 & 8.6
	20 & 12.2
\end {tabular}


\section {Analysis}

A linear fit to the measurements yields
 \begin {equation}
x=(0.598 ({+\over -}) 0.05 {\rm cm/s})t-0.02 {\rm cm}
\end {equation}

where x is the position of the insect and t is the time.

\section {Conclusion}

The insect does not walk as fast as humans.
