In five trials of walking along a 90-m course on fairly level ground, a pacer for a survey party counted 51, 52.5, 51.5, 52.5 and 51.5 strides respectively. He then started walking an unknown distance XY in four trials which were recorded as follows: 88.5, 89, 88, and 87 strides. Determine the following: a.) Pace factor of the pacer b.) Length of line XY c.) Percentage of error in the measurement if the taped length of XY is 150.5 meters.
