PACE FACTOR AND PACED DISTANCE DETERMINATION

Pacing is one of many methods of measurement. We can measure distance through pace factor. Pace factor is equivalent to distance covered per pace. Using this, estimated distance could be determined.

Estimated Distance = (Number of Paces)(Pace Factor)

Determination of Pace Factor

In this activity, pace factor was measured through walking on 50-m distance in UP Academic Oval and the number of paces it took was counted. Five trials was made and the average of paces for the trials was computed in order to get the pace factor. Data were tabulated on Table 1.

Determination of the Perimeter of Melchor Hall through Pacing

Next part would be the determination of the lengths of the sides of the engineering block using pacing. Using the pace factor, lengths would be obtained. Values were compared to the real lengths of the sides. Perimeter of the building was computed and compared to actual value. Measurements are shown in Table 2 and Figure 1. Table 2. Data from Pacing
