A 60 – m track, AB, on level ground was paced by Peter Parker for the purpose of determining his own pace factor. The numbers of paces for each trial taken are: Trial 1 - 81 paces Trial 2 - 79 paces Trial 3 - 78 paces Trial 4 - 80 paces Trial 5 - 82 paces Trial 6 - 80 paces Determine the following: 1. Mean number of paces 2. Peter Parker's pace factor 3. If Peter Parker walked on another track with the following no. of paces: 117, 123, 121, 119, and 120, what is the most probable distance of the new track.

Mapping

Mapping is the process of representing the surface of the earth, objects on it, and the relative positions of the objects, to a suitable scale. In mapping, a large area of land is measured, surveyed, and plotted. The details of the objects present in the nearby surrounding area are located using conventional signs. All these processes are carried out on a flat paper known as a map.
