Step-by-step explanation:
Given:
- Each side of the pitch (AB, BC, CD, DA) is of equal length.
- The points A, B, C, D, E, and F mark distinct positions on the pitch.
Sketches of the Graphs
Exercise 1
Both Harry and Jack run clockwise, so they start from A and C respectively and follow the perimeter of the field.
The distance between them decreases initially as they run towards each other and then increases after they pass each other.
The graph will show:
- A decrease from the initial distance to the minimum when they meet.
- An increase back to the initial distance as they complete the circuit.
Exercise 2
Harry runs clockwise and Jack runs anticlockwise, so they start from A and C respectively and run in opposite directions.
The distance between them increases initially as they run in opposite directions and then decreases after they pass each other.
The graph will show:
- An increase from the initial distance to the maximum when they are at opposite ends.
- A decrease back to the initial distance as they complete the circuit.
Exercise 3
Harry runs to D, and Jack runs to F. Since the paths are different and not forming a circuit:
The distance will vary linearly as they move along the straight lines towards their respective points.
The graph will show:
A linear increase or decrease depending on their relative positions and paths.
