1. In 5 trials of walking along a 90 m course on level ground, a pacer for a survey party counted 50, 51.5, 50.5, 51.5 and 52.5 strides respectively. He then started walking an unknown distance XY in four trials which were recorded as follows: 89.5, 89, 88.5, 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.
